Short Answer

Determine the Appropriate Hypothesis Test to Perform
-The table below shows the weights, in pounds, of seven subjects before and after following a particular diet program for three months. Does the sample evidence suggest that the diet program is effective in reducing weight? Use the $\alpha = 0.01$ level of significance. Assume that the differenced data come from a population that is normally distributed with no outliers.
$\begin{array}{r|ccccccc}\text { Subject } & \text { A } & \text { B } & C & \text { D } & \text { E } & \text { F } & \text { G } \\\hline \text { Before, } \mathrm{X}_{\mathrm{i}} & 183 & 160 & 193 & 184 & 188 & 151 & 185 \\\hline \text { After, } \mathrm{Y}_{\mathrm{j}} & 176 & 151 & 191 & 189 & 174 & 153 & 173\end{array}$
