Question
Abby Kratz, a market specialist at the market research firm of Saez, Sikes, and Spitz, is analyzing household budget data collected by her firm. Abby's dependent variable is weekly household expenditures on groceries (in $'s), and her independent variables are annual household income (in $1,000's) and household neighborhood (0 = suburban, 1 = rural). Regression analysis of the data yielded the following table.| Coefficients | Standard Error | t Statistic | p-value | |
| Intercept | 19.68247 | 10.01176 | 1.965934 | 0.077667 |
| X1 (income) | 1.735272 | 0.174564 | 9.940612 | 1.68E-06 |
| X2 (neighborhood) | 49.12456 | 7.655776 | 6.416667 | 7.67E-05 |
Abby's model is ________________.
a) y = 19.68247 + 10.01176 x1 + 1.965934 x2
b) y = 1.965934 + 9.940612 x1 + 6.416667 x2
c) y = 10.01176 + 0.174564 x1 + 7.655776 x2
d) y = 19.68247 - 1.735272 x1 + 49.12456 x2
e) y = 19.68247 + 1.735272 x1 + 49.12456 x2

Accordingly, she has designed an experiment to test her theory using four sales discount rates (0%, 2%, 4%, and 6%). First, she classified DCI's credit customers into three categories by total assets (small, medium, and large). Then, she randomly assigned four customers from each category to a sales discount rate. In Cindy's experiment "sales discount rate" is ________.
