Instruction 19-5
The director of the MBA program of a university wanted to know if a one week orientation would change the proportion among potential incoming students who would perceive the program as being good. Given below is the result from 215 students' view of the program before and after the orientation.
After the Orientation
$$\begin{array} { | c | c | c | c | }
\hline \text { Before the Orientation } & \text { Good } & \text { Not Good } & \text { Total } \
\hline \text { Good } & 93 & 37 & 130 \
\hline \text { Not Good } & 71 & 14 & 85 \
\hline \text { Total } & 164 & 51 & 215 \
\hline
\end{array}$$
-Referring to Instruction 19-5,the null hypothesis for the Friedman rank test for the difference in the means should be rejected at a 0.01 level of significance.

The question mentions the Friedman rank test for the difference in means, which is a nonparametric test used to determine if there are differences in ranked data over multiple groups. The result provided shows a significant change in perception among potential incoming students from before to after the orientation. Therefore, the null hypothesis that there is no difference in perception before and after the orientation can be rejected at a 0.01 level of significance. Hence, the answer is A.
