question 64

Multiple Choice

Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is $\mu _ { \mathrm { d } } = 0$ . Compute the value of the $t$ test statistic.
- $$\begin{array} { c | c c c c c c c c } \mathrm { x } & 7.1 & 5.9 & 3.4 & 10.3 & 4 & 10.2 & 9.3 & 7.1 \\\hline \mathrm { y } & 5.3 & 5.6 & 4.5 & 5.6 & 4.4 & 4.9 & 5.4 & 5.4\end{array}$$

• A)t = 6.792
• B)t = 0.998
• C)t = 2.391
• D)t = 0.845
