Question

Randomly selected birth records were​ obtained, and categorized as listed in the table to the right. Use a 0.01 significance level to test the reasonable claim that births occur with equal frequency on the different days of the week. How might the apparent lower frequencies on Saturday and Sunday be​ explained?

Day	Sunday	Monday	Tuesday	Wednesday	Thursday	Friday	Saturday
Number of Births	50	58	65	64	59	56	35

Determine the null and alternative hypotheses:

Calculate the test statistic X² (Round 3 decimal places):

Calculate the P-value (Round to 4 decimal places)

What is the conclusion for this hypothesis test?

A. Fail to reject H0. There is sufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week.

B. Reject H0. There is sufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week.

C. Reject H0. There is insufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week.
