The Data Below Represent the Weight Losses for People on Three

question 44

Essay

The data below represent the weight losses for people on three different exercise programs. $$\begin{array} { c c c } \text { Exercise A } & \text { Exercise B } & \text { Exercise C } \\\hline 2.5 & 5.8 & 4.3 \\8.8 & 4.9 & 6.2 \\7.3 & 1.1 & 5.8 \\9.8 & 7.8 & 8.1 \\5.1 & 1.2 & 7.9\end{array}$$ If we want to test the claim that the three size categories have the same means, why don't we use three separate
hypothesis tests for $\mu _ { 1 } = \mu _ { 2 } , \mu _ { 2 } = \mu _ { 3 } \text {, and } \mu _ { 1 } = \mu _ { 3 } \text { ? }$
