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
