Relationship Between Energy Consumption and Temperature Refer to the data in Exercise 3 and the data used for Exercises 2–4 in Section 13-2. Match the data in pairs according to the corresponding time periods.

a. Is there a significant linear correlation between the amounts of electrical energy consumption and the temperatures? Explain.

b. Identify the linear regression equation that relates electrical energy consumption (y) and the temperature (x).

c. What is the best predicted amount of electrical energy consumption for a twomonth period with an average temperature of 60°F?
