Textbook Question
Chapter 7.2, Problem 1E
Each month for several months, the average temperature in °C (x) and the number of pounds of steam (y) consumed by a certain chemical plant were measured. The least-squares line computed from the resulting data is y = 245.82 + 1.13x.
- a. Predict the number of pounds of steam consumed in a month where the average temperature is 65°C.
- b. If two months differ in their average temperatures by 5°C, by how much do you predict the number of pounds of steam consumed to differ?
