For Exercises 15–24, use the data and the regression equations that you calculated in the Section 13.1 exercises.

Question 13.95

17. World Temperatures. For the data from Exercise 41 in Section 13.1, do the following:

  1. Predict the population mean high temperature for a city with a low temperature of 30 degrees.
  2. Construct a 99% confidence interval for the population mean high temperature for all cities with a low temperature of 30 degrees.
