Use the StatCrunch output provided to answer the following (parts a-g. The output was obtained by using a person’s foot length (cm) to predict their height (cm) for a sample of 40 people.

a. What is the correlation between foot length and height?

b. Estimate the change in the mean height when the foot length increases by one cm. Use a 95% confidence interval.

c. Conduct a hypothesis test to determine if there is a linear association between X and Y. Use α = .05.

d. Obtain and interpret a 95% confidence interval for the mean height for a people with a foot length of 25.5 cm..

e. Obtain a 95% prediction interval for a person that has a foot length of 26.2.

f. One person had a foot length of 25.4 cm and a height of 165.7 cm. Find the residual for this observation.

g. Give and interpret (in context) the coefficient of determination for this problem.
