Question

A random group of used books was selected from a book warehouse to analyze the books' condition. The book store believes that $26 \%$ of the books are in excellent condition, $36 \%$ are in very good condition, $21 \%$ are in fair condition, and $17 \%$ are in poor condition. Is there evidence to reject this hypothesis at = .05 ? $\begin{array}{lcccc} \text { Book condition } & \text { Excellent } & \text { Very good } & \text { Fair } & \text { Poor } \ \text { Number of books } & 22 & 25 & 19 & 8 \end{array}$ A) There is not evidence to reject the claim that the books are distributed as claimed because the test value $2.935 < 7.815$ B) There is evidence to reject the claim that the books are distributed as claimed because the test value $7.815 > 2.935$ C) There is not evidence to reject the claim that the books are distributed as claimed because the test value $2.935 < 9.488$ D) There is evidence to reject the claim that the books are distributed as claimed because the test value $9.488 > 2.935$

The test value $2.935$ is less than the critical value $7.815$ for a chi-square test with 3 degrees of freedom at the 0.05 significance level, indicating there is not enough evidence to reject the hypothesis.
