1.Using the information below calculate the predicted value for Y for the given value of X.

Y (Dependent Variable) = Grade Point Average

X (Independent Variable) = Average number of hours spent studying per week

yhat = 2 +0.196*X

On average what would a person's Grade Point Average be if they spend on average 8 hours studying per week(round your answer to 4 decimal places)?

2.Using the information below calculate the predicted value for Y for the given value of X.

Y (Dependent Variable) = Cost of a car in thousands of dollars (i.e. Y = 1 means one-thousand dollars)

X (Independent Variable) = Miles per Gallon in city traffic

yhat = 28.1 + 0.62*X

On average how many thousands of dollars would a car cost if it gets 15 Miles per Gallon in city traffic(round your answer to 4 decimal places)?

3.Select the appropriate interpretation for the slope of the linear regression equation below.

Y (Dependent Variable) = Cost of an annual pass to Disney in dollars

X (Independent Variable) = Average number of people who visit each day in thousands of people

yhat = 2122.86 - 30*X

Group of answer choices

a.There is not enough information to answer this question

b.For every 1 dollar more that a Disney annual pass costs then on average the daily attendanceat the park has decreased by 30 thousand people.

c.For every 1 dollar less that a Disney annual pass costs then on average the daily attendance at the park has increased by 30 thousand people.

d.For every 1 thousand more people on average who visit Disney each day then the price of an annual pass will increase on average by 30 dollars

e.For every 1 thousand more people on average who visit Disney each day then the price of an annual pass will decrease on average by 30 dollars

f.The independent variable does not have a significant influence on the dependent variable
