Can the consumption of water in a city be predicted by temperature? The following data represent a sample of a day's water consumption and the high temperature for that day.

Water Use Temperature

(millions of gallons) (degrees Fahrenheit)

219 ............. 103◦

56 .............39

107 .............77

129 .............78

68 .............50

184 .............96

150 .............90

112 .............75

Develop a least squares regression line to predict the amount of water used in a day in a city by the high temperature for that day. What would be the predicted water usage for a temperature of 100_? Evaluate the regression model by calculating se , by calculating r 2, and by testing the slope. Let = .01.
