Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is $\mu _ { \mathrm { d } } = 0.$ 0. Compute the value of the t test statistic. Round intermediate calculations to four decimal places as needed and final answers to three decimal places as needed.
-$\begin{array}{c|cccccccc}
\mathrm{x} & 6.7 & 6.3 & 4.1 & 11.4 & 4.2 & 11.7 & 9.1 & 6.6 \
\hline \mathrm{y} & 4.9 & 6 & 5.2 & 6.7 & 4.6 & 6.4 & 5.2 & 4.9
\end{array}$
A) $t = 6.792$
B) $t = 0.998$
C) $t = 0.845$
D) $t = 2.391$

The t test statistic is calculated using the differences between paired samples. The mean of these differences, the standard deviation of the differences, and the number of pairs are used to compute the t value. After performing these calculations, the t value is approximately 2.391.
