Steps in Hypothesis Testing: Videos & Practice Problems

In a library study, the next $24$ borrowed books are recorded. If the books were borrowed randomly by genre, you would expect a $50/50$ split between fiction and nonfiction. However, only $7$ of the books are fiction. Assume $n=24$, $p=0.5$, and use a two-tailed test with $\alpha =0.05$. The critical values for this test are $x\le 8$ or $x\ge 16$. Should you reject the null hypothesis? What do you conclude about the borrowing pattern?
