Pleаse uplоаd yоur scrаtch wоrk for this question after finishing the test. Suppose the table below give data on the number of lamps in 9 homes as well as the average monthly energy bills for those 9 homes. This data will be used to predict the average monthly energy bill based on the number of lamps in the home. (a) What is the equation of the regression line for this data set? (b) Should you use your line to predict the average monthly energy bill of a home that has 12 lamps in the home? If so, make the prediction. If not, explain why.
