On average, 79% of American fathers are in the delivery room when their children are born. A physician€™s assistant surveyed 300 first-time fathers to determine if they had been in the delivery room when their children were born. The results are shown here. At α = 0.05, is there enough evidence to reject the claim that the proportions of those who were in the delivery room at the time of birth are the same?

Perform the following steps.
a. State the hypotheses and identify the claim.
b. Find the critical value.
c. Compute the test value.
d. Make the decision.
e. Summarize the results.
Use the traditional method of hypothesis testing unless otherwise specified.
