Determine the null and alternative hypotheses.
Ho:
Calculate the test statistic, x2.
x2 =

Calculate the P-value.
P-value =
(Round to four decimal places as needed.)
What is the conclusion for this hypothesis test?
A. Reject Ho: There is insufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week.
B. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week.
O C. Fail to reject Ho. There is insufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week.
D. Reject Ho: There is sufficient evidence to warrant rejection of the 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?
O A. Induced or Caesarean-section births are scheduled during the week whenever possible.
O B. Induced or Caesarean-section births are scheduled on weekends whenever possible.
