The Following Summary Is from Home Heating Costs, Using Mean

Multiple Choice

The following summary is from home heating costs, using mean outside temperature as X₁ the number of centimetres of insulation as X₂, and the presence of a garage as X₃. Is the presence of the independent variable garage significant in predicting heating costs, when tested at the 0.05 level of significance?

A) Since the p-value is less than the level of significance, the null hypothesis is rejected, and so the garage should be included in the analysis.
B) Since the p-value is less than the level of significance, the null hypothesis is accepted, and so the garage should not be included in the analysis.
C) Since the p-value is more than the level of significance, the null hypothesis is accepted, and so the garage should not be included in the analysis.
D) Since the p-value is more than the level of significance, the null hypothesis is rejected, and so the garage should be included in the analysis.
