Question

The data below represent the weight losses for people on three different exercise programs.

Exercise A	Exercise B	Exercise C
xbar = 6.7	xbar = 4.16	xbar = 6,46
s = 2.94	s =2.94	s =1.58
n = 5	n = 5	n = 5

At the 1% significance level, do the data provide sufficient evidence that a difference exists in the true mean weight loss produced by the three exercise programs? Perform a critical value test. (Assume all assumptions satisfied.)

Hypotheses:

Test statistic:

Source	Sum of Squares	df	Mean Square	F
Between Groups
W/in Groups (error)
Total

Critical-value:

Conclusion:
