# Question

Refer to Exercise 11.22 to complete the following.

a. Predict the time to run 10 km if an athlete has a treadmill time of 11 minutes.

b. Place a 95% prediction interval on the time to run 10 km for an athlete having a treadmill time of 11 minutes.

c. Compare the 95% prediction interval from part (b) to the 95% confidence interval from Exercise 11.36. What is the difference in the interpretation of these two intervals? Provide a nontechnical reason why the prediction interval is wider than the confidence interval.
