\text { Mean SSATL Score } & 65.75 & 79.83 \
\text { Population Std. Dev. } & 11.07 & 6.41 \
\hline
\end{array}$$
-Referring to Table 10-1, judging from the way the data were collected, which test would likely be most appropriate to employ?
A) related samples Z test for the mean difference
B) paired t test
C) pooled-variance t test for the difference between two means
D) independent samples Z test for the difference between two means
