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 |
For the same number of website visitors, what is difference between the predicted sales for MP3 versus "˜other" heavy metal song downloads
a) $1,566,666 higher sales for "˜other" formats
b) the same sales for both formats
c) $1,566,666 lower sales for the "˜other" format

Q:
Collinsville Construction Company purchases steel rods for its projects. Based on previous tests, Claude Carter, Quality Assurance Manager, has recommended purchasing rods from Redding Rods, Inc. (population 1), rather than Stockton Steel (population 2), since Redding's rods had less variability in length. Recently, Stockton revised it rod shearing operation, and Claude has sampled the outputs from Redding's and Stockton's rod manufacturing processes. The results for Redding were s12= 0.15 with n1= 8, and, for Stockton, the results were s22= 0.05 with n2= 10. Assume that rod lengths are normally distributed in the population. If a= 0.05, the appropriate decision is _________.
a) reject the null hypothesis 12 = 22
b) reject the null hypothesis 12 < 22
c) do not reject the null hypothesis 12 = 22
