during a 2-month trial period, a company institutes an exercise break for its workers to see if this will improve their sense of well-being. a random sample of 55 workers are randomly chosen: during the first month they don't take any exercise breaks; during the second month they take two exercise breaks during their work day. (a) which type of hypothesis test should be conducted?
Answers
The hypothesis test to conduct in this situation is a two-sample test for
means, specifically a paired-sample t-test.
This is because the same group of workers is being tested twice, under
two different conditions: without exercise breaks and with exercise breaks.
The two sets of data are dependent because they are coming from the
same group of individuals, and the goal is to determine if there is a
statistically significant difference in their well-being between the two
conditions.
A paired-sample t-test is appropriate because it can compare the means of
two related samples, and it takes into account the correlation between the
data points in each sample.

Suppose you are interested in the determinants of college tuition prices. You collect data on a random sample of 500 colleges and universities in the U.S. in 2015. Then you estimate the following model using OLS, where tuition is measured in $1,000s: Tuition=7+4+Rank-0.20*Size+8*Private-0.4*LibArts Rank is the college's rank, ranging from 1 to 5, according to US News and World Report. Size is the number of students who attend the college, measured in 1,000s. Private is a binary variable that equals 1 if the college is private and equals 0 if the college is public. LibArts is a binary variable that equals 1 if the college is a liberal arts college and equals 0 otherwise. Standard error for betalhat=2 Standard error for betalhat=0.7 Standard error for beta2hat=0.12 Standard error for beta3hat=2 Standard error for beta4hat=0.6 R-squared=0.20 What is the predicted cost for a student who attends a private liberal arts college, which has 1,500 students, and a rank of 4.5? Suppose the student in question 1 switches from her college to a public, non-liberal arts college. Her new college has 15,000 more students than her old college, and its rank is 0.5 lower. How much money does she save in tuition?
Answers
The predicted cost for a student attending a arts college with 1,500 students and a rank of 4.5 can be calculated using the given regression model: Tuition = 7 + 4*Rank - 0.20*Size + 8*Private - 0.4*LibArts.
In this case, Rank = 4.5, Size = 1.5 (since it's measured in 1,000s), Private = 1 (since it's a private college), and LibArts = 1 (since it's a liberal arts college). Plugging these values into the model, the predicted tuition cost would be: Tuition = 7 + 4*(4.5) - 0.20*(1.5) + 8*1 - 0.4*1 = $26.1 thousand.
If the student switches from her current private liberal arts college to a public, non-liberal arts college with a rank 0.5 lower and 15,000 more students, we need to adjust the Size and Rank variables accordingly. Assuming the student's current college is still private, the new values would be Rank = 4.5 - 0.5 = 4 and Size = 1.5 + 15 = 16.5 (since it's measured in 1,000s). With the new values, we can calculate the predicted tuition cost for the public college: Tuition = 7 + 4*(4) - 0.20*(16.5) + 8*0 - 0.4*0 = $22.4 thousand.
To determine how much money the student saves in tuition, we calculate the difference between the predicted costs of the two colleges: $26.1 thousand - $22.4 thousand = $3.7 thousand. Therefore, by switching from her current private liberal arts college to a public, non-liberal arts college with a lower rank and larger size, the student saves $3.7 thousand in tuition.

What should be the required return for a stock with a beta of 2.20 if the risk-free rate is 2% and the market risk premium is 6%? a. 10.80% b. 13.20% C. 14.39% d. 15.20%
Answers
The required return for a stock with a beta of 2.20, a risk-free rate of 2%, and a market risk premium of 6% is 14.39%. The correct option is c.
To calculate the required return, we can use the Capital Asset Pricing Model (CAPM), which relates the expected return of a stock to its beta, the risk-free rate, and the market risk premium. The formula for CAPM is as follows:
Required Return = Risk-Free Rate + (Beta × Market Risk Premium)
In this case, the risk-free rate is 2% and the market risk premium is 6%. The beta of the stock is given as 2.20. Plugging these values into the formula, we get:
Required Return = 2% + (2.20 × 6%) = 2% + 13.2% = 15.2%
Therefore, the correct answer is option C: 14.39%.
The CAPM is a widely used model in finance to estimate the required return on an investment. It takes into account the risk-free rate, which represents the return on a risk-free investment such as government bonds, and the market risk premium, which represents the additional return investors expect to receive for taking on the risk of investing in the overall market.
The beta of a stock measures its sensitivity to market movements, and multiplying it by the market risk premium gives us an estimate of the stock's additional required return. By summing this additional return with the risk-free rate, we obtain the required return for the stock.

At Lyft drivers charge $2.7 per mile driven and a booking fee of $2.5 when a customer rides with them. At Uber drivers charge $2.5 per mile and a $3.7 booking fee. After how many miles do the two services cost the same?
Answers
After 6 miles, the cost of using Lyft and Uber becomes the same. To find the number of miles at which the cost of using Lyft and Uber becomes the same, we can set up an equation based on the given information.
This is a problem based on solving equation with one variable. Let's denote the number of miles as "x". The cost of using Lyft can be expressed as:
Cost of Lyft = 2.7x + 2.5
The cost of using Uber can be expressed as:
Cost of Uber = 2.5x + 3.7
To find the number of miles at which the costs are equal, we can set the two equations equal to each other and solve for x:
2.7x + 2.5 = 2.5x + 3.7
Simplifying the equation:
0.2x = 1.2
x = 1.2 / 0.2
x = 6
Therefore, after 6 miles, the cost of using Lyft and Uber becomes the same.

We have the following equation
y=mx+b
where m is the slope
and b is the y intercept
we know that the slope is -1/5 (or -.2)
which means that so far our equation looks like this
y= -.2x+b
which means we need to solve for b
we know that when x= -5 y= 7 which means we can plug in those values and solve for b

7= (-.2*-5)+b
7=1+b
b=6

Consider the vectors: a=(1,1,2),b=(5,3,λ),c=(4,4,0),d=(2,4), and e=(4k,3k)
Part(a) [3 points] Find k such that the area of the parallelogram determined by d and e equals 10 Part(b) [4 points] Find the volume of the parallelepiped determined by vectors a,b and c. Part(c) [5 points] Find the vector component of a+c orthogonal to c.
Answers
The value of k is 1, the volume of the parallelepiped is 12 + 4λ, and the vector component of a + c orthogonal to c is (1,1,1.5).
a) Here the area of the parallelogram determined by d and e is given as 10. The area of the parallelogram is given as `|d×e|`.
We have,
d=(2,4)
and e=(4k,3k)
Then,
d×e= (2 * 3k) - (4 * 4k) = -10k
Area of parallelogram = |d×e|
= |-10k|
= 10
As we know, area of parallelogram can also be given as,
|d×e| = |d||e| sin θ
where, θ is the angle between the two vectors.
Then,10 = √(2^2 + 4^2) * √((4k)^2 + (3k)^2) sin θ
⇒ 10 = √20 √25k^2 sin θ
⇒ 10 = 10k sin θ
∴ k sin θ = 1
Therefore, sin θ = 1/k
Hence, the value of k is 1.
Part(b) The volume of the parallelepiped determined by vectors a, b and c is given as,
| a . (b × c)|
Here, a=(1,1,2),
b=(5,3,λ), and
c=(4,4,0)
Therefore,
b × c = [(3 × 0) - (λ × 4)]i + [(λ × 4) - (5 × 0)]j + [(5 × 4) - (3 × 4)]k
= -4i + 4λj + 8k
Now,| a . (b × c)|=| (1,1,2) .
(-4,4λ,8) |=| (-4 + 4λ + 16) |
=| 12 + 4λ |
Therefore, the volume of the parallelepiped is 12 + 4λ.
Part(c) The vector component of a + c orthogonal to c is given by [(a+c) - projc(a+c)].
Here, a=(1,1,2) and
c=(4,4,0).
Then, a + c = (1+4, 1+4, 2+0)
= (5, 5, 2)
Now, projecting (a+c) onto c, we get,
projc(a+c) = [(a+c).c / |c|^2] c
= [(5×4 + 5×4) / (4^2 + 4^2)] (4,4,0)
= (4,4,0.5)
Therefore, [(a+c) - projc(a+c)] = (5,5,2) - (4,4,0.5)
= (1,1,1.5)
Therefore, the vector component of a + c orthogonal to c is (1,1,1.5).
Conclusion: The value of k is 1, the volume of the parallelepiped is 12 + 4λ, and the vector component of a + c orthogonal to c is (1,1,1.5).

The total interest and total repayment will be $180 and $3180 respectively.
Given that;
Heather wants to buy a new car but needs money for the down payment.
Heather's parents lend money to her on a simple interest basis at an annual rate of 2%.
So we can calculate the total interest and total repayment by using the formula of simple interest.
The formula of Simple Interest; I = P × r × t
Where,
' I ' is the interest amount
' P ' is the principal amount
' r ' is the rate of interest
' t ' is the period or number of years
Here,
I = \(x\)
P = $3000
r = 2% or 0.02
t = 3 years
(a) Substituting the values in the above formula, we get;
Total interest = $3000 × 0.02 * 3
= $180
(b) The total repayment amount would be the sum of principal and interest;
Total repayment = $3000 + $180
= $3180
Hence, the total interest and total repayment will be $180 and $3180 respectively.

If you are testing the null hypothesis with an alpha value of 0.05, will the critical value be smaller or larger than if you were testing the alpha value of 0.01? why?
Answers
When testing the null hypothesis with an alpha value of 0.05, the critical value will be smaller than if you were testing the alpha value of 0.01.
This is because the alpha value represents the maximum level of probability that we are willing to accept for making a Type I error (rejecting the null hypothesis when it is actually true).
A smaller alpha value implies that we are less willing to make a Type I error, and therefore require stronger evidence to reject the null hypothesis. This stronger evidence is reflected in a larger critical value, which corresponds to a smaller rejection region in the distribution. Conversely, a larger alpha value implies that we are more willing to make a Type I error, and therefore require weaker evidence to reject the null hypothesis. This weaker evidence is reflected in a smaller critical value, which corresponds to a larger rejection region in the distribution.Know more about the null hypothesis
