The question is...

Assume that the populations are normally distributed with the same variance.
15) The data below represent the weight losses for people on three different exercise programs.
Exercise A treatment total: 33.5, n = 5

Exercise B treatment total: 20.8,  n = 5

Exercise C  treatment total: 32.3, n = 5


CF = 499.971, N = 15, and SStotal = 98.789
Use the treatment totals and the given values to find the test stat and critical value to test (at the 1% significance level) if it appears that a difference exists between the true mean weight loss produced by the three exercise programs?
A) Test statistic: F = 0.249. Critical value: F = 5.8266.
B) Test statistic: F = 1.243. Critical value: F = 6.9266.
C) Test statistic: F = 1.491. Critical value: F = 99.416.
D) Test statistic: F = 1.491. Critical value: F = 6.9266.
E) Test statistic: F = 1.491. Critical value: F = 2.8068.

D) Test statistic: F = 1.491. Critical value: F = 6.9266.
