Short Answer

Test Hypotheses Regarding Matched-Pairs Data
-Data sets $\mathrm { A }$ and $\mathrm { B }$ are dependent. Test the claim that $\mu _ { \mathrm { d } } = 0$ . Use $\alpha = 0.05$ .
$\begin{array}{c|lllll}\text { A } & 37 & 35 & 54 & 50 & 38 \\\hline \text { B } & 35 & 31 & 32 & 42 & 29\end{array}$

Assume that the paired data came from a population that is normally distributed.
