Twenty college students experience the effects of alcohol on reaction time. They perform very basic timed responses in a driving simulator both before and after consuming several alcoholic beverages. The researcher collects a reaction-time result for each of the 20 students before and after intoxication, for a total of 40 measures. What is the null hypothesis for this paired-samples study?
Answer:
For this case the hypothesis would be that after consuming alcoholic beverages the reaction time increases, so then the system of hypothesis for this case are:
The system of hypothesis for this case are:
Null hypothesis: [tex]\mu_y- \mu_x \leq 0[/tex]
Alternative hypothesis: [tex]\mu_y -\mu_x >0[/tex]
We can define the difference as: [tex]d_i=y_i-x_i[/tex]
And the system of hypothesis are:
Null hypothesis:[tex] \mu_d \leq 0[/tex]
Alternative hypothesis: [tex] \mu_d >0[/tex]

Ryan is building a ramp so he can easily move things in and out of an overhead storage area in his garage. The storage area is 8 feet off the ground, and Ryan has 15 feet of space along the ground to build the ramp.
A triangle with side lengths 15 feet, 8 feet, and an unlabeled hypotenuse.
What is the length of the ramp Ryan will build?
7 feet
10 feet
17 feet
23 feet
Answer:
17 feet
Step-by-step explanation:
c=the length of the ramp
a=8 ft
b=15 ft
Pythagorean Theorem
c²=a²+b²
c²=8²+15²
c²=64+225
c²=289
c=√289
c=17 ft
The length of the ramp of the triangular path is AC = 17 feet
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the ramp is BC = 15 feet
The height of the ramp is AB = 8 feet
So , length of the ramp Ryan needs to build is AC is
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
AC = √ ( AB )² + ( BC )²
AC = √ ( 8 )² + ( 15 )²
AC = √ ( 64 + 225 )
AC = √289
AC = 17 feet
Therefore , the value of AC is 17 feet
Hence , the length of the ramp is 17 feet

The combination of Wendell and Maggie’s ages is 33. Wendell’s age is 3 less than 3 times the age of Maggie. How old is Wendell?
Answer:
Wendell is 24 years old.
Step-by-step explanation:
First write an equation to represent the situation.
x=Maggie's age
x+(3x-3)=33
Then solve for x
x+3x-3=33
4x-3=33
4x-3+3=33+3
4x=36
4x/4=36/4
x=9
Then solve for Wendell's age
y=Wendell's age
y=3x-3
y=3(9)-3
y=27-3
y=24
Wendell is 24 years old.
By setting up and solving a system of equations based on the information given, we find that Wendell is 24 years old.
Explanation:In this question, we are asked to find out Wendell's age. First, we assume that Maggie's age is x. According to the problem, the sum of Wendell and Maggie's ages is 33, so we can write the first equation as Wendell's age + Maggie's age = 33. Next, we know that Wendell's age is three less than three times Maggie's age, so Wendell's age = 3*x - 3. Now, if we insert Wendell's age expression from the second equation into the first equation, we get 3*x - 3 + x = 33. When we solve this equation, we found that x equals to 9, hence, Maggie is 9 years old. That means, Wendell is 33 - 9 = 24 years old.

Talulah is an ecologist who studies the change in the penguin population of Antarctica over time. She observed that the population decays by a factor of 8/9 every 4 months. The population of penguins can be modeled by a function, P, which depends on the amount of time, t (in months). When Talulah began the study, she observed that there were 27,000 penguins in Antarctica. Write a function that models the population of the penguins t months since the beginning of Talulah's study. P(t) =
Answer:
P(t) = 27000 * (8/9)^(t/4)
Step-by-step explanation:
The population of penguins in Antarctica decays by 8/9 every 4 months, starting from an initial count of 27,000. The function for the penguin population P(t) after t months is P(t) = 27,000 × (8/9)^(t/4).
Explanation:Talulah, an ecologist, has observed that the population of penguins in Antarctica decays by a factor of 8/9 every 4 months. To model this decay, we can use an exponential decay function. Given that the initial population (P0) is 27,000 penguins, the function P(t) that models the population at time t (in months) since the beginning of Talulah's study is:
P(t) = P0 × (decay factor)(t/rate period)
Where P0 is the initial population, the decay factor is 8/9, and the rate period is 4 months. Plugging in these values gives us:
P(t) = 27,000 × (8/9)(t/4)
This function allows researchers to predict the penguin population at any given time t months after Talulah's initial observation.

A bank offer 3% interest each yr you invest 1500. Write a equation to model this situation for x years. How much will be in the account after 10 years?
Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 1500
r = 3% = /100 = 0.0
n = 1 because it was compounded once in a year.
t = x years
Therefore, the equation to model this situation is
A = 1500(1 + 0.03/1)^1 × x
A = 1500(1.03)^x
When x = 10 years, then
A = 1500(1.03)^10
A = $2016
The heights (in cm) and arm spans (in cm) of 31 students were measured. The association between (height) and (arm span) is shown in the scatterplot below. The equation of the line of best fit modeling this relationship is given:
y=4.5+0.977x
Mike is 172 cm tall and George is 165 cm tall. Using the model, how many centimeters longer would we expect Mike's arm span to be than George's? Round your answer to the thousandths place.
Answer: Mike's arm span is 7.165 cm longer than the George's one.
Step-by-step explanation:
We have that the association between height and arm span is modeled by the equation
y = 4.5 + 0.977*x
where y is height and x is arm span.
Mike is 172 cm tall, so his arm span is:
172cm = 4.5 + 0.977*x
x = (172 - 4.5)/0.977 = 171.443 cm
and George is 165 cm tall, so his arm span is:
x = (165 - 4.5)/0.977 = 164.278 cm
Then the difference between their arm span is:
171.443cm - 164.278cm = 7.165 cm
So Mike's arm span is 7.165 cm longer than the George's one.

A manufacturer of cheese filled ravioli supplies a pizza restaurant chain. Based on data collected from its automatic filling process, the amount of cheese inserted into the ravioli is normally distributed. To make sure that the automatic filling process is on target, quality control inspectors take a sample of 25 ravioli and measure the weight of cheese filling. They find a sample mean weight of 15 grams with a standard deviation of 1.5 grams. What is the margin of error at 90% confidence?
A. 0.3 grams
B. 0.5133 grams
C. 0.8391 grams
D. 1.5 grams
E. 0.06 grams
Answer:
A.0.39 grams
margin of error at 90% confidence intervals is
M.E = 0.39 grams
Step-by-step explanation:
Explanation:-
Given a sample of size n = 25
mean of the sample x⁻ = 15 grams
Standard deviation of the sample 'S' = 1.5 grams
margin of error at 90% confidence intervals is determined by
[tex]Margin error = \frac{t_{0.90} S.D}{\sqrt{n} }[/tex]
The degrees of freedom ν = n-1 = 25-1 =24
The tabulated value t₀.₉₀ = 1.318
[tex]Margin error = \frac{1.318X 1.5}{\sqrt{25} }[/tex]
Margin of error = 0.3954
Conclusion:-
Margin of error at 90% confidence intervals = 0.3954
