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 Sun Mon Tues Wod Thurs Fn Sat D Number of Births 37 58 60 64 55 56 42 Calculate the test statistic, x x =(Round to three decimal places as needed.) Calculate the P-value. P.value =(Round to four decimal places as needed.) What is the conclusion for this hypothesis test? O 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 O B. 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 O D. 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. 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
