Transcribed Image Text:Preliminary data analyses indicate that it is
reasonable to consider the assumptions for
one-way ANOVA satisfied. Use Minitab to
perform the required hypothesis test using the
p-value approach.
The data below represent the weight losses for
people on three different exercise programs.

a difference exists in the true mean weight loss
produced by the three exercise programs?
Op = 0.264
Fail to reject the claim of equal means
OP=0.0024
Reject the claim of equal means
