Test Hypotheses Regarding Two Population Standard Deviations
-A study was conducted to determine if the variances of librarian salaries from two neighboring cities were equal. A sample of 25 librarians from each city was selected. The first city had a standard deviation of s $1 =$ $\$ 3680$ , and the second city had a standard deviation $s _ { 2 } = \$ 3360$ . Test the hypothesis that the variances of the salaries from both cities are equal. Use $\alpha = 0.05$ Assume the samples were randomly selected from normal populations.
