Answer to Question #55683 in Statistics and Probability for Asanga

Question

The Energy study was conducted over a six year period to investigate factors which could be used to predict the net hourly energy output of a power plant. The Minitab file, Energy.mtw, which is on iLearn consists of a randomly selected sample of 100 observations recorded during the course of the study. Each observation consists of information recorded on the following variables.
Variable Description
AirTemp Hourly average air temperature (°C)
Energy Net hourly electrical energy output (megawatts)




a. Use the Minitab file, Energy.mtw, to fit a linear regression model for predicting energy output from air temperature. Cut and paste the following output into the space below:
i. Appropriate Minitab plots for checking each of the three assumptions of a linear model. Do not use the ‘four in one’ graph option in Minitab. Comments on each of these assumptions should go into your report on the following page.
ii. The regression analysis of Energy vs AirTemp from Minitab
