Explanation / Answer
Result:
The accompanying SAS computer output relates to the sales revenue data from Problem 11 in Chapter 8. Use this output and, if necessary, the output for Problem 10 in Chapter 9 to answer the following questions.
a. Determine r2Y|X1,X2, the squared multiple correlation between sales revenue (Y) and the independent variables TV advertising expenditures (X1) and print advertising expenditures (X2).
R square = RSS/ TSS
=28.11853/28.83333
=0.975209246
97.52% of variation in sales revenue (Y) are explained by the independent variables TV advertising expenditures (X1) and print advertising expenditures (X2).
