Question
Alan Bissell, a market analyst for City Sound Online Mart, is analyzing sales from heavy metal song downloads. Alan's dependent variable is annual heavy metal song download sales (in $1,000,000's), and his independent variables are website visitors (in 1,000's) and type of download format requested (0 = MP3, 1 = other). Regression analysis of the data yielded the following tables.| Coefficients | Standard Error | t Statistic | p-value | |
| Intercept | 1.7 | 0.384212 | 4.424638 | 0.00166 |
| x1(website visitors) | 0.04 | 0.014029 | 2.851146 | 0.019054 |
| x2(download format) | -1.5666667 | 0.20518 | -7.63558 | 3.21E-05 |
Alan's model is ________________.
a) y = 1.7 + 0.384212 x1 + 4.424638 x2 + 0.00166 x3
b) y = 1.7 + 0.04 x1 + 1.5666667 x2
c) y = 0.384212 + 0.014029 x1 + 0.20518 x2
d) y = 4.424638 + 2.851146 x1 - 7.63558 x2
e) y = 1.7 + 0.04 x1 - 1.5666667 x2

Q:
Cindy Ho, VP of Finance at Discrete Components, Inc. (DCI), theorizes that the discount level offered to credit customers affects the average collection period on credit sales. 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 ________.
