# Question

Refer to the temperature data given in the table accompanying Exercise 12.

a. Using Excel, a calculator, or other software, find the intercept and slope for the regression equation with x = average June temperature and y = average December temperature for these cities.

b. Use the equation you found in part (a) to predict the average December temperature for a city with an average June temperature of 70 degrees. What assumption is required about the city in question, in order for this to be a relatively accurate prediction?

c. Do you think the equation you found in part (a) could be used to predict average December temperature from June temperature for Honolulu, Hawaii? Explain.
