Chapter 9, Problem 1CT

Net Sales The equation used to predict the net sales (in millions of dollars) for a fiscal year for a clothing retailer is

$\hat{y}=23,769+9.18x_1-8.41x_2$

where x₁ is the number of stores open at the end of the fiscal year and x₂ is the average square footage per store. Use the multiple regression equation to predict the y-values for the values of the independent variables.

1. (a) x₁= 1057, x₂ = 3698
2. (b) x₁ = 1012, x₂ = 3659
3. (c) x₁ = 952, x₂ = 3601
4. (d) x₁ = 914, x₂ = 3594
