Multiple Choice

Shape-Up-By-Susie claims that participating in her exercise program will result in guaranteed weight loss in just 6 weeks. Five clients weighed themselves before and then
Again after participating in her program and the differences "weight after - weight
Before" were analyzed. Based on the relevant computer output shown below, we can say Paired T for After - Before
$\begin{array} { l c r r r } & \mathrm { N } & \text { Mean } & \text { StDev } & \text { SE Mean } \\ \text { After } & 5 & 144.6 & 31.7 & 14.2 \\ \text { Before } & 5 & 148.0 & 28.9 & 12.9 \\ \text { Difference } & 5 & - 3.40 & 3.51 & 1.57 \end{array}$
$95 \%$ upper bound for mean difference: $- 0.06$
$\mathrm { T }$ -Test of mean difference $= 0 ( \mathrm { vs } < 0 ) : \mathrm { T }$ -Value $= - 2.17 \mathrm { P }$ -Value $= 0.048$
