Question

A random group of students was selected from a large student conference to analyze their class in school Is there evidence to reject the hypothesis that the number of students is equally distributed between the $\begin{array} { c c c c c c } & \text { Year in school } & \text { Freshman } & \text { Sophomore } & \text { Junior } & \text { Senior } \ \text { four classes, at } = .05 ? & \text { Number of students } & 12 & 9 & 15 & 20 \end{array}$ A)There is evidence to reject the claim that students are equally distributed between the four classes . because the test value $7.815 > 4.714$ B)There is not evidence to reject the claim that students are equally distributed between the four classes . because the test value $4.714 < 9.488$ C) There is evidence to reject the claim that students are equally distributed between the four classes . because the test value $9.488 > 4.714$ D)There is not evidence to reject the claim that students are equally distributed between the four classes . because the test value $4.714 < 7.815$ .

The chi-square test value of 4.714 is less than the critical value of 7.815 at a 0.05 significance level, indicating there is not enough evidence to reject the hypothesis of equal distribution.
