electricity for a twelve year period. The data measure the following: Electricity Residential rate per kilowatt hour Natural Gas Residential natural gas per 1000 cubic feet Fuel Oil Residential fuel oil per gallon Gasoline Regular gasoline per gallon Your model will attempt to predict residential electricity costs using the cost of the other fuels. (1) State whether you would expect a positive or negative relationship between electricity costs and each of the independent variables and explain why. (2) Use EXCEL, to create a correlation using all independent variables provided. Discuss all aspects of the correlation matrix, as it compares to your expectations in part (a) and what it tells you about the potential results of a regression analysis.
