Essay

Perform the required correlation test for normality.
-Twelve students were selected at random from a college class and were asked how many hours they had studied for a particular test. The results are as follows. $\begin{array} { l l l l l l } 2.1 & 3.6 & 8.4 & 6.6 & 6.0 & 4.8 \end{array}$ $\begin{array} { l l l l l l } 11.5 & 7.1 & 12.0 & 5.9 & 8.0 & 4.2 \end{array}$
At the 5% significance level, do the data provide sufficient evidence to conclude that study times of students in this class are not normally distributed?
