Question
A sample of 117 records of the selling price in dollars of homes from Feb 15 to Apr 30, 2013was taken from the files maintained by the Albuquerque Board of Realtors. The following are
summary statistics for the selling prices.
| Variable | N | Mean | Minimum | Q1 | Median | Q3 | Maximum |
| Prices | 117 | 106270 | 54000 | 77650 | 96000 | 121750 | 215000 |

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
