Answer:

(a) The outlier in the data is $810.

(b) The distribution of money spent on textbooks for the 34 students is right skewed.

Step-by-step explanation:

The data provided for the amount of money 34 college students spent on books is:

S = {120, 130, 130, 140, 150, 150, 160, 170, 180, 210, 220, 230, 240, 250, 260, 280, 280, 290, 290, 290, 310, 320, 320, 370, 380, 390, 410, 440, 450, 470, 510, 530, 620, 810}

(a)

An outlier of a data set is a value that is very different from the other values of a data set. It is either too large or too small.

The most common way to determine whether a data set consists of any outliers of not is,

Here

Q₁ = first quartile

Q₃ = third quartile

IQR = Inter-quartile range = Q₃ - Q₁.

The first quartile is the value that is more than 25% of the data values. The first quartile is the median of the first half of the data.

Compute the value of first quartile as follows:

First half of data: {120, 130, 130, 140, 150, 150, 160, 170, 180, 210, 220, 230, 240, 250, 260, 280, 280}

There are 17 values.

The median of an odd data set is the middle value.

The middle value is: 180

The first quartile is Q₁ = 180.

The third quartile is the value that is more than 75% of the data values.

Compute the value of first quartile as follows:

Second half of data: {290, 290, 290, 310, 320, 320, 370, 380, 390, 410, 440, 450, 470, 510, 530, 620, 810}

There are 17 values.

The median of an odd data set is the middle value.

The middle value is: 390

The third quartile is Q₃ = 390.

Compute the inter-quartile range as follows:

IQR = Q₃ - Q₁

      = 390 - 180

      = 210

Compute the value of [Q₁ - 1.5 IQR] as follows:

[tex]Q_{1}-1.5\ IQR =180-(1.5\times 210)=-135[/tex]

Compute the value of [Q₃ + 1.5 IQR] as follows:

[tex]Q_{3}+1.5\ IQR =390+(1.5\times 210)=705[/tex]

There are no values that are less than [Q₁ - 1.5 IQR]. But there is one value that is more than [Q₃ + 1.5 IQR].

X = 810 > [Q₃ + 1.5 IQR] = 705

Thus, the outlier in the data is $810.

(b)

A distribution is known as to be skewed to the right, or positively skewed, when maximum of the data are collected on the left of the distribution.

In the stem plot above, it is shown that maximum of the data values are collected on the left of the chart. This implies that the distribution is positively skewed.

Thus, the distribution of money spent on textbooks for the 34 students is right skewed.

Outliers are data elements that are relatively far from other data elements

(a) The outlier

From the plot, the stems are given as:

Stems: 1 2 3 4 5 6 7 8

However, stem 7 does not have any leaf

Using the above highlight, the next entry after 620 is 810

810 is relatively far from the other datasets.

Hence, 810 is an outlier

(b) The distribution

The data on the stem-plot is more concentrated at the top, and it reduces as the stem increases.

When there are more data elements at the top or left, then the distribution is right skewed.

Hence, the distribution is right skewed.

Answer:

(a) The estimated proportion of defective in the population is 0.05.

(b) The 95% confidence interval for the proportion defective cups is (2.5%, 7.5%).

(c) Zack does not needs to return the lots.

Step-by-step explanation:

Let X = number of defective cups.

The random sample of cups selected is of size, n = 300.

The number of defective cps in the sample is, X = 15.

(a)

The proportion of the defective cups in the population can be estimated by the sample proportion because the sample selected is quite large.

The sample proportion of defective cups is:

[tex]\hat p=\frac{X}{n}=\frac{15}{300}=0.05[/tex]

Thus, the estimated proportion of defective in the population is 0.05.

(b)

The (1 - α)% confidence interval for population proportion is:

[tex]CI=\hat p \pm z_{\alpha/2}\times\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

Compute the critical value of z for 95% confidence level as follows:

[tex]z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96[/tex]

Compute the 95% confidence interval for p as follows:

[tex]CI=\hat p \pm z_{\alpha/2}\times\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

     [tex]=0.05 \pm 1.96\times\sqrt{\frac{0.05(1-0.05)}{300}}[/tex]

     [tex]=0.05\pm 0.025\\=(0.025, 0.075)\\[/tex]

Thus, the 95% confidence interval for the proportion defective cups is (2.5%, 7.5%).

(c)

It is provided that Zack has an agreement with his supplier that he is to return lots that are 10% or more defective.

The 95% confidence interval for the proportion defective is (2.5%, 7.5%). This implies that 95% of the lots have 2.5% to 7.5% defective items.

Thus, Zack does not needs to return the lots.

The estimated proportion of defective in the population is 0.05 and the 95 percent confidence interval for the proportion defective is (0.025,0.075).

Given :

a) The formula given below is used in order to determine the estimated proportion of defective in the population.

[tex]\hat{p} = \dfrac{X}{n}[/tex]

[tex]\hat{p} = \dfrac{15}{300}[/tex]

[tex]\hat{p} = 0.05[/tex]

So, the estimated proportion of defective in the population is 0.05.

b) The below formula is used in order to determine the 95 percent confidence interval for the proportion defective.

[tex]CI =\hat{p}\pm z_{\alpha /2}\times \sqrt{ \dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]

Now, substitute the known terms in the above expression.

[tex]CI =0.05 \pm 1.96\times \sqrt{ \dfrac{0.05(1-0.05))}{300}}[/tex]

[tex]CI = 0.05\pm 0.025[/tex]

So, the 95 percent confidence interval for the proportion defective is (0.025,0.075).

c) According to the given data, Zack has an agreement with his supplier that he is to return lots that are 10 percent or more defective.

So, from the above calculation, it can be concluded that he did not have to return the lots.

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be parallel, they need to have the same slope.

[tex]y=-\frac{2}{3} x+12[/tex]    The slope is -2/3, so the parallel line's slope is also -2/3.

Now that you know the slope, substitute/plug it into the equation.

y = mx + b

[tex]y=-\frac{2}{3} x+b[/tex]   To find b, plug in the point (6, -11) into the equation, then isolate/get the variable "b" by itself

[tex]-11=-\frac{2}{3}(6)+b[/tex]

-11 = -4 + b     Add 4 on both sides to get "b" by itself

-7 = b

[tex]y=-\frac{2}{3} x-7[/tex]    

The slope-intercept form line that passes through the point (6, -11) and is parallel to the line y = -2/3x + 12 is y = -2/3x - 7.

The subject of this question is Mathematics, specifically algebra and geometry involving slope-intercept form. The question asks for the slope-intercept form of the line that passes through the given point (6, -11) and is parallel to the line y = -2/3x + 12.

In slope-intercept form, y = mx + b, m represents the slope of the line and b represents the y-intercept. We know that parallel lines have the same slope, so the slope of the line in question would be -2/3, same as the provided line.

To find the y-intercept (b), we use the point (6, -11) and the slope -2/3 in the slope-intercept equation: -11 = (-2/3) * 6 + b. Solving for b, we get b = -7. Hence, the equation of the line in slope-intercept form that passes through the given point and is parallel to the given line is y = -2/3x - 7.

Step-by-step explanation:

Given:

Here Section 1 students = 20

Section 2 students = 30

Here there are 15 graded exam papers.

(a )Here Pr(10 are from second section) = ²⁰C₅ * ³⁰C₁₀/⁵⁰C₁₅= 0.2070

(b) Here if x is the number of students copies of section 2 out of 15 exam papers.

 here the distribution is hyper-geometric one, where N = 50, K = 30 ; n = 15

Then,

Pr( x ≥ 10 ; 15; 30 ; 50) = 0.3798

(c) Here we have to find that at least 10 are from the same section that means if x ≥ 10 (at least 10 from section B) or x ≤ 5 (at least 10 from section 1)

so,

Pr(at least 10 of these are from the same section) = Pr(x ≤ 5 or x ≥ 10 ; 15 ; 30 ; 50) = Pr(x ≤ 5 ; 15 ; 30 ; 50) + Pr(x ≥ 10 ; 15 ; 30 ; 50) = 0.0140 + 0.3798 = 0.3938

Answer: after driving 330 miles, the remaining fuel in each tank be the same.

Step-by-step explanation:

Let x represent the number of miles it will take for the the remaining fuel in each tank to be the same.

Jerry has a large car which holds 22 gallons of fuel and gets 20 miles per gallon. It means that the number of gallons needed to drive 1 mile is 1/20. Then the number of gallons needed to drive x miles is

1/20 × x = x/20

If the tank is full, then the number of gallons of fuel left after driving x miles is

22 - x/20

Kate has a smaller car which holds 16.5 gallons of fuel and gets 30 miles per gallon. It means that the number of gallons needed to drive 1 mile is 1/30. Then the number of gallons needed to drive x miles is

1/30 × x = x/30

If the tank is full, then the number of gallons of fuel left after driving x miles is

16.5 - x/30

For the remaining fuel in each tank to be the same, it means that

22 - x/20 = 16.5 - x/30

Multiplying both sides of the equation by 60(LCM), it becomes

1320 - 3x = 990 - 2x

- 2x + 3x = 1320 - 990

x = 330 miles

[tex]\theta_{2} = \frac{5\pi}{3} \pm 2\pi\cdot i[/tex], [tex]\forall i \in \mathbb{N}_{O}[/tex]

Step-by-step explanation:

The critical numbers are found by the First Derivative Test, which consists in differentiating the function, equalizing it to zero and solving it:

[tex]g'(\theta) = 16 - 4\cdot \sec^{2} \theta[/tex]

Following equation needs to be solved:

[tex]16 - 4\cdot \sec^{2}\theta = 0[/tex]

[tex]\sec^{2}\theta = 4[/tex]

[tex]\cos^{2}\theta = \frac{1}{4}[/tex]

[tex]\cos \theta = \frac{1}{2}[/tex]

The solution is:

[tex]\theta = \cos^{-1} \frac{1}{2}[/tex]

Given that cosine is a periodical function, there are two subsets of solution:

[tex]\theta_{1} = \frac{\pi}{3} \pm 2\pi\cdot i[/tex], [tex]\forall i \in \mathbb{N}_{O}[/tex]

[tex]\theta_{2} = \frac{5\pi}{3} \pm 2\pi\cdot i[/tex], [tex]\forall i \in \mathbb{N}_{O}[/tex]

The critical numbers of the function g(θ) = 16θ − 4 tan(θ) can be found by determining where the derivative of the function is zero or undefined. However, specific critical numbers can't be determined from the provided prompt due to complexity of the derivative.

The critical numbers of a function occur when the derivative of the function is equal to zero or undefined. Given the function g(θ) = 16θ − 4 tan(θ), the first step to be done is finding the derivative (g'(θ)) of the function.

This involves applying the rules of differentiation to each term: the coefficient rule (b), and chain rule for the tangent part. After calculating the derivative, we set g'(θ) equal to zero and solve for θ to determine the critical numbers. For the term involving tan(θ), it is undefined at θ = π/2 + πn, where n is an integer. Therefore, these are also considered as critical numbers.

However, due to the complexity of the derivative, finding critical numbers usually requires using algebraic and trigonometric techniques or potentially numerical methods if the equation cannot be solved analytically. As the specific steps for this complex derivative calculation are not provided in the prompt, we can't provide the specific critical numbers.

The capability of the process is determined using the process capability index (Cp). In this case, the process has a capability of 0.833, indicating that it is not meeting the specifications well.

To calculate the capability of the process, we need to use the process capability index (Cp). Cp is calculated by dividing the tolerance range by six times the standard deviation. The tolerance range in this case is 65 - 55 = 10 psi. So, Cp = 10 / (6 * 2) = 10 / 12 = 0.833. Since Cp is a measure of how well the process meets the specifications, a value closer to 1 indicates a better capability.

In this case, the process has a capability of 0.833, which means it is not meeting the specifications very well.

The process capability index (Cpk) for the grease aerosol can pressurization process is 0.67, indicating that the process is not capable of meeting the design specifications as it is less than the acceptable limit of 1.33.

The capability of the process in question relates to its ability to meet design specifications, which can be quantified using statistical measures like the process capability index (Cpk). To compute the Cpk, you need to determine the worst-case process capability scenario by comparing the distance of the process mean to the nearest specification limit in terms of standard deviations. The Cpk can be calculated using the formula:

Cpk = minimum [(USL - x) / (3σ), (x - LSL) / (3σ)]

Where USL is the upper specification limit, LSL is the lower specification limit, x is the process mean, and σ is the standard deviation.

For this process with an average of 61 psi and a standard deviation of 2 psi:

You would calculate two separate indices:

Thus, the Cpk would be the smaller of these two indices which is 0.67. A Cpk of 0.67 indicates that the process is not capable of meeting the design specifications since it is less than the acceptable limit of 1.33 for most industries.

Answer:

5(8-x)

Step-by-step explanation:

Fact using the GCF (Greatest Common Factor) of 40 and 5

Factors of 5:

1,5

Factors of 40:

1,2,4,5,8,10,20,40

The greatest factor they both have is 5

Factor by distributing out a 5

40-5x

5(8-x)

The GCF (Greatest Common Factor) of 40 and 5 is 5!

Divide both numbers by 5.

40 / 5 = 8

-5x / 5 = -x

Rewrite the expression using the distributive property.

5(8 - x)

Best of Luck!
