Answer:

Hence, the minimum required sample size (n) should be = 1692

Step-by-step explanation:

Solution:-

- The estimation error, E = 2%

- The confidence level, CI = 90 %

- Since the proportion of the positive lab tests for prostate cancer are actually proven correct through subsequent biopsy are unknown we will assume the corresponding proportion to be p = 0.58

- The required sample size is a function of confidence value and error of estimation (E):

                            [tex]n = p*( 1 - p ) * (\frac{Z-critical}{E})^2[/tex]        

Where,

- The critical value of the confidence level = 90% would be:

          significance level ( α ) = 1 - CI = 1 - 0.90 = 0.1

          Z-critical = Z_α/2 = Z_0.05 = 1.645  

- The required sample size (n) can be calculated:

           [tex]n = 0.5*( 1 - 0.5 ) * (\frac{1.645}{0.02})^2\\\\n = 1691.265[/tex]

- Hence, the minimum required sample size (n) should be = 1692

Answer:

1. The median is a much more precise measure of the team's perfomance & it showcases the true picture of the team's average performance

2. This implies that Armand needs to  train for 23 minutes on Sunday

Step-by-step explanation:

The mean (also called arithmetic mean) is the central value of a given set of data; gotten by dividing the sum of the values in the data set by the number of items in the data set.

Mathematically,

Mean (m) = ∑ [tex]\frac{x_i}{n}[/tex]

where [tex]x_{i}[/tex] = the sample

           n = the number of items in the sample

The median is the central value in a distribution or given set of data after the data has been arranged sequentially either in ascending or descending degree. In simpler terms, it is regarded as the 'middle number'. The basic advantage of the median over the mean is that unlike the mean which can be skewed by outliers (extremely high or low values) in a data set, the median stays close to presenting a true value

1.

Data for the basketball team in its last 5 games = 73, 70, 72, 71, 130

Mean (m) = (73 + 70 + 72 + 71 + 130) ÷ 5

Mean (m) = 416 ÷ 5 = 83.2

Arranging the data sequentqially, we have: 70, 71, 72, 73, 130

Median ([tex]{\displaystyle a}[/tex]) = 72

The median is a much more precise measure of the team's perfomance & it showcases the true picture of the team's average performance. The mean was skewed by the result of the team's last game where the team scored 130 points (an outlier)

2.

Armand's training data (the week begins on Monday & ends on Sunday):

Monday = 53 minutes, Tuesday = 24 minutes, Wednesday = 35 minutes,

Thursday = 60 minutes, Friday = 20 minutes, Saturday = 65 minutes,

Sunday = ?

Since Armand intends to practise an average of 40 minutes for the week (7 days), we calculate thus

Mean (m) = sum of time Armand spends training ÷ number of days Armand spends training

Target Mean = 40 minutes, sum of time = 53 + 24 + 35 + 60 + 20 + 65 + x = 257 + x

where x = minutes Armand needs to practice on Sunday to meet his goal

number of days = 7

40 = (257 + x) ÷ 7

Make x the subject of the formula, we have:

257 + x = 40 * 7

x = 280 - 257 = 23

x = 23 minutes

This implies that Armand needs to  train for 23 minutes on Sunday if he is to make his targeted weekly average of 40 minutes

Answer:

16

Step-by-step explanation:

It's hard to tell what the what the problem means by "not like the others", but here's a guess.

None of the other numbers are perfect squares.

Also, 16 is not divisible by 3. All other numbers are divisible by 3.

Answer:

Charlton is the snoozer!

Step-by-step explanation:

"If Charlton is telling the truth, that means that both Davis and Rawls are the liars; in particular, Vongy is telling the truth, which would mean that Bobbins is also a liar, contradicting the fact that there are only two liars and there three truth-tellers.

So Charlton is lying. That means that at most one of Davis and Rawls are lying.

If Bobbins is telling the truth, then the second liar must be one of Rawls and Davis, which would again mean that Vongy is telling the truth, making Bobbins a third liar; this is impossible, so Bobbins is lying.

So we now know that the two liars are Charlton and Bobbins, and the remaining three are truth-tellers.

Therefore, the snoozer is either Rawls or Charlton (since Davis is telling the truth), but cannot be Rawls (since Rawls is telling the truth).

So Charlton is the one who fell asleep."

Answer:

By eliminating Linens department net operating income fell by $574,800.00

Step-by-step explanation:

The question requires that the monthly contribution income statement be prepared when the Linens is closed or eliminated,incorporating the unavoidable fixed costs of $373,000 as well as the fall in sales of Hardware by 15%.

             Monthly Contribution Income Statement:

Sales($3,110,000)*(1-15%)                               $2,643,500.00  

Variable expenses($858,000)*(1-15%)          ($729,300.00)

Contribution margin                                        $1,914,200.00  

Fixed expenses($1,480,000+$373,000)      ($1,853,000.00)

Net operating income                                        $61,200.00  

Reduction in net operating=$636,000-$61,200.00=$574,800  

Alternatively:

Lost contribution from closing Linens department    $674,000.00

Lost contribution from Hardware(15%*$2,252,000)   $ 337,800.00  

Total lost contribution                                                   $1,011,800.00  

Less avoidable fixed costs($810,000-$373,000)         ($437,000.00)

Reduction in profits company-wide                                $574,800.00  

The sunk costs, allocated costs, and the impact on the Hardware Department's sales and profitability, dropping the Linens Department appears to be a financially prudent decision for Bed & Bath.

Sunk Costs and Allocated Costs:
- $373,000 of the fixed expenses allocated to the Linens Department are sunk costs or allocated costs. These costs will continue even if the Linens Department is dropped. They should not be considered in the decision-making process as they will not change with the elimination of the department.

2. Impact on Hardware Department:
- Dropping the Linens Department will result in a 15% decrease in the sales of the Hardware Department. This means that the sales of the Hardware Department will decrease by $1,110,000 (15% of $3,110,000, Linens sales). This decrease in sales will impact the contribution margin of the Hardware Department.

3. Contribution Margin Calculation:
- The contribution margin of the Hardware Department before dropping Linens is $2,252,000. With a 15% decrease in sales, the new contribution margin for the Hardware Department is $1,142,000.

4. Net Operating Income:
- The net operating income of the Hardware Department after dropping the Linens Department is calculated by subtracting the fixed expenses of the Hardware Department and the revised contribution margin from the total sales.

5. Overall Impact:
- Dropping the Linens Department will result in a positive impact on the overall net operating income of Bed & Bath. The increased net operating income from the Hardware Department ($772,000) will offset the loss from dropping the Linens Department ($136,000).

Considering the sunk costs, allocated costs, and the impact on the Hardware Department's sales and profitability, dropping the Linens Department appears to be a financially prudent decision for Bed & Bath.

Incomplete question check attachment for diagram

Step-by-step explanation:

Two parallel lines, cross by a transversal

The angle between one of the line and the transfer is 125° and this angle is opposite to angle d, so it is vertical opposite angle

Vertically Opposite Angles are the angles opposite each other when two lines cross, so it was the transversal line that cross the parallel lines

Answer:

The point at which the line y  = 2.5·x + 3 intersect with the circle of radius 4 and center (0, 3) is x = 1.49

Step-by-step explanation:

Here we have the equation of a circle = (x - h)² + (y-k)² = r²

Where (h, k) is the coordinate of the center

Therefore, we have

(x - 0)² + (y - 3)² = 4²

Which gives x² + (y - 3)² = 16

Since the line y  = 2.5·x + 3 we have

x² + ( (2.5·x + 3 ) - 3)² = 16

x² + (2.5·x)² = 16

x² + 6.25·x² = 16

7.25·x² = 16

x² = 16/7.25 = 2.21

x = 1.49

That is the line y  = 2.5·x + 3 intersect with the circle of radius 4 and center (0, 3) at x = 1.49.

The point of intersection in the first quadrant of the given line y = 2.5x + 3 and the given circle x² + (y - 3)² = 16, can be found by substituting the equation of the line into the equation of the circle and then solving for x and y.

The subject of this question is the intersection of a line and a circle in the first quadrant of a coordinate plane. The circle is defined by the equation (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius. For a circle with center at the origin (0, 3) and radius 4, the equation is x² + (y - 3)² = 16.

The line is defined by the equation y = 2.5x + 3. To find the intersection point, we substitute this equation into the equation of the circle, resulting in x² + (2.5x)² - 6x + 9 = 16. Solving this quadratic equation gives the x-coordinates of the intersection points. Since we are only interested in the first quadrant, we pick the positive root. Substituting this value of x into y = 2.5x +3 gives the corresponding y-coordinate, defining the point of intersection in the first quadrant.

Answer:

10 sundaes will be vanilla.

Step-by-step explanation:

Given:

Fernando is making 30 sundaes with mint, chocolate,and vanilla ice cream.

1/3 of the Sunday's are mint ice-cream.

And 1/2 of the remaining sundaes are chocolate.

The rest are vanilla.

Now, to find the number of sundaes that will be vanilla.

Fernando is making sundaes total = 30.

So, the quantity of sundaes that are mint ice-cream:

[tex]\frac{1}{3} \ of\ 30\\\\=\frac{1}{3} \times 30\\\\=10.[/tex]

Thus, 10 sundaes are mint ice-cream.

So, the remaining sundaes are:

[tex]30-10=20.[/tex]

Thus, the remaining sundaes are = 20.

Now, to get the quantity of chocolate sundaes of the remaining sundaes:

[tex]\frac{1}{2} \ of\ 20\\\\=\frac{1}{2} \times 20\\\\=10.[/tex]

Hence, 10 sundaes are chocolate of the remaining 20 sundaes.

As, given the rest are vanilla.

Now, to get the vanilla sundaes we subtract the 10 chocolate ice-cream from the 20 remaining sundaes:

[tex]20-10=10.[/tex]

Therefore, 10 sundaes will be vanilla.

Answer:

0.5

Step-by-step explanation:

Solution:-

- The sample mean before treatment, μ1 = 46  

- The sample mean  after treatment, μ2 = 48

- The sample standard deviation σ = √16 = 4

- For the independent samples T-test, Cohen's d is determined by calculating the mean difference between your two groups, and then dividing the result by the pooled standard deviation.

                           Cohen's d = [tex]\frac{u2 - u1}{sd_p_o_o_l_e_d}[/tex]

- Where, the pooled standard deviation (sd_pooled) is calculated using the formula:

                          [tex]sd_p_o_o_l_e_d =\sqrt{\frac{SD_1^2 +SD_2^2}{2} }[/tex]

- Assuming that population standard deviation and sample standard deviation are same:

                          SD_1 = SD_2 =  σ = 4

- Then,

                           [tex]sd_p_o_o_l_e_d =\sqrt{\frac{4^2 +4^2}{2} } = 4[/tex]

- The cohen's d can now be evaliated:

                          Cohen's d = [tex]\frac{48 - 46}{4} = 0.5[/tex]

Final answer:

0.5, representing a medium effect size.

Explanation:

To calculate Cohen's d, we use the formula:

d = (M1 - M2) / SD

Where M1 is the mean of the population before treatment, M2 is the mean after treatment, and SD is the standard deviation of the population. Given that M1 = 46, M2 = 48, and the sample variance is σ2 = 16, we first need to find the standard deviation (SD), which is the square root of the variance.

SD = sqrt(σ2) = sqrt(16) = 4

Next, we apply the values to Cohen's d formula:

d = (48 - 46) / 4

d = 2 / 4 = 0.5

This gives us a Cohen's d value of 0.5, which indicates a medium effect size according to Cohen's benchmarks.

The diameter of this circle is 10, the circumference is 31.4 and the area is 58.5.

Because the diameter of a circle is twice its radius, we have:

d = 2*r

d = 2*5 = 10

The following formula calculates the circumference of a circle:

2*pi*r = circumference

2*3.14*5 circumference

10 times 3.14 equals 31.4

The following formula calculates the area of a circle:

area = pi*r²

area = 3.14*(5)²

area = 3.14*25

area = 78.5

This circle has a diameter of 10, a circumference of 31.4, and an area of 58.5.

Answer:

It will take 9 hours with 4 painters  to paint 720 feet of  fence.

Step-by-step explanation:

Given that,

The time needed to paint a fence varies directly with the length of the fence

[tex]t\propto l[/tex] .......(1)

and inversely with the number of painters

[tex]t\propto \frac1P[/tex].....(2)

Combination of (1) and (2) is

[tex]t\propto \frac lP[/tex]

where t represents time, [tex]l[/tex] represents length of fence, P represents number of painters.

Again we can write the above equation as

[tex]\frac{t_1}{t_2}=\frac{\frac{l_1}{l_2}}{\frac{P_1}{P_2}}[/tex]

[tex]\frac{t_1}{t_2}=\frac{l_1P_2}{l_2P_1}[/tex]

Given that,

It takes 7 hours with 2 painters  to paint 280 feet of fence .

We need to find time to paint 720 feet of fence with 4 painters.

[tex]t_1[/tex]=7  hours, [tex]l_1[/tex]=280 feet, [tex]P_1[/tex]=2,

[tex]t_2[/tex]=? , [tex]l_2[/tex] = 720 feet, [tex]P_2[/tex]=4

[tex]\therefore \frac{7}{t_2}=\frac{280\times 4}{720\times 2}[/tex]

[tex]\Rightarrow \frac{t_2}{7}=\frac{720\times 2}{280\times 4}[/tex]

[tex]\Rightarrow {t_2}}=\frac{720\times 2\times 7}{280\times 4}[/tex]

[tex]\Rightarrow t_2=9[/tex]

It will take 9 hours to paint 720 feet of  fence with 4 painters.

The time it takes for four painters to paint a 720 feet fence is calculated using direct and inverse variation, resulting in 9 hours, using the constant of variation determined from the initial condition provided by the student.

Direct and Inverse Variation in Painting Jobs

The student's question involves direct and inverse variation, which means we need to solve for the time based on the length of the fence and the number of painters. Initially, it takes seven hours for two painters to paint 280 feet of fence. This scenario sets up our proportion. When the length of the fence and the number of painters changes, the time to paint the fence will also change according to the direct and inverse relationships.

To find the time it takes for four painters to paint 720 feet of fence we use the formula [tex]T = (k \times L) / P[/tex], where T is the time needed, L is the length of the fence, P is the number of painters, and k is a constant of variation. Using the initial condition, we can solve for k by rearranging the formula to [tex]k = (T \times P) / L[/tex]. Substituting the initial condition values, we find that [tex]k = (7 hours \times2 painters) / 280 feet[/tex], which simplifies to k = 1/20.

To find the time it will take for four painters to paint 720 feet, we use the formula with our calculated constant of variation and the new conditions: T = (1/20 × 720 feet) / 4 painters, which gives us T = 9 hours. Therefore, it will take four painters 9 hours to paint 720 feet of fence.
