A Random Group of Seniors Was Selected from a University $50 \%$

question 64

Multiple Choice

A random group of seniors was selected from a university and asked about their plans for the following year. The school advising office claims that $50 \%$ of the students plan to work, $20 \%$ of the students plan to continue in school, and $30 \%$ of the students plan to take some time off. Is there evidence to reject this hypothesis at $\alpha = 0.05$ ?
$\begin{array} { l c c c } \text { Plans } & \text { Work } & \text { School } & \text { Time off } \\ \text { Number of students } & 21 & 13 & 8 \end{array}$

• A) There is evidence to reject the claim that the students' plans are distributed as claimed because the test value 4.198 < 5.991
• B) There is evidence to reject the claim that the students' plans are distributed as claimed because the test value 4.198 < 7.815
• C) There is not evidence to reject the claim that the students' plans are distributed as claimed because the test value 4.198 < 5.991
• D) There is not evidence to reject the claim that the students' plans are distributed as claimed because the test value 4.198 < 7.815
