SCENARIO 18-2
One of the most common questions of prospective house buyers pertains to the cost of heating in dollars (Y) . To provide its customers with information on that matter, a large real estate firm used the following 4 variables to predict heating costs: the daily minimum outside temperature in degrees of Fahrenheit ( X₁ ) , the amount of insulation in inches ( X ₂ ) , the number of windows in the house ( X₃ ) , and the age of the furnace in years ( X ₄ ) . Given below are the EXCEL outputs of two regression models.

A) Do not reject H0 and conclude that the amount of insulation has a linear effect on heating cots. B) Reject H0 and conclude that the amount of insulation does not have a linear effect on heating costs. C) Reject H0 and conclude that the amount of insulation has a negative linear effect on heating costs. D) Do not reject H0 and conclude that the amount of insulation has a negative linear effect on heating costs.$
