There is interest at the American Savings and Loan as to whether there is a difference between average daily balances in checking accounts that are joint accounts (two or more members per account)versus single accounts (one member per account).To test this,a random sample of checking accounts was selected with the following results:
Based upon these data,the test statistic for testing whether the two populations have equal variances is F = 1.3733.

The test statistic F is used to test the hypothesis of equal variances between two populations. The null hypothesis is that the populations have equal variances, and the alternative hypothesis is that they do not. In this case, the calculated value of F is 1.3733, which is not greater than the critical value at any common significance level. Therefore, we fail to reject the null hypothesis and conclude that there is no significant difference between the variances of the two populations at a given level of significance.
