In an effort to better understand current donation patterns, the manager of a public broadcast radio station 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, the manager has selected random samples of 25 men and 25 women from people who donated during last year’s telethon.

The following statistics were computed from the sample data:

Males Females x = +12.40 x = +8.92 s = +2.50 s = +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?
