Test Hypotheses Regarding Matched-Pairs Data
-Data Sets a and B $\mu _ { \mathrm { d } } = 0$

Short Answer

Test Hypotheses Regarding Matched-Pairs Data
-Data sets A and B are dependent. Test the claim that $\mu _ { \mathrm { d } } = 0$ . Use $\alpha = 0.01$ .
$\begin{array}{c|ccccc}\text { A } & 7.1 & 8.1 & 10.0 & 7.0 & 7.1 \\\hline \text { B } & 9.5 & 8.4 & 8.3 & 8.2 & 9.6\end{array}$

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