The manager of the Public Broadcasting System for Tennessee is considering changing from the traditional week-long contribution campaign to an intensive one day campaign. In an effort to better understand current donation patterns, she is studying past data. A staff member from a neighboring state has speculated that male viewer's donations have greater variability in amount than do those of females. To test this, random samples of 21 men and 15 women were selected from people who donated during last year's telethon, and the sample standard deviations of males and females were $3.5 and $2.2, respectively. Based on these sample data, is there sufficient evidence to conclude that male viewer's donations have larger variability in amount than do those of female viewers?Use a significant level of 0.05.

I.The type of hypothesis test (lower-tailed, upper-tailed, two-tailed) to conduct for this study is:

II. The value of the test statistics to conduct the test is:

III. The critical value obtained from the table is:

V.The conclusion for this test is (Reject Ho, Fail to Reject Ho):

VI.Can we concludethat male viewer's donations have larger variability in amount than do those of female viewers(Yes,Insufficient evidence )?:
