The manager of the Public Broadcasting System for Tennessee is considering changing from the traditional weeklong 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 viewers' donations have greater variability in amount than do those of females. To test this, random samples of 25 men and 25 women were selected from people who donated during last year's telethon. The following statistics were computed from the sample data:

Male/ Female

1 = 12.401 = 8.92

1 = 2.502 = 1.34

Based on a significance level of 0.05, does it appear that male viewers' donations have greater variability in amount than do those of female viewers? F0.05 = 1.984
