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.

The Answer is critical values

t _ { 0 } = \pm 4.604

; standardized test statistic

\mathrm { t } \approx - 1.215

; fail to reject

\mathrm { H } _ { 0 }

; There is not sufficient evidence to reject the claim.
