4. 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 Wed Thurs Sat Number of Births 35 57 62 60 61 57 48 Determine the null and alternative hypotheses. Hy: (1) H: (2) Calculate the test statisti, x? x2 = (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. OB. 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. OC. Fail to reject Hy. There is sufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week. OD. 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 on weekends whenever possible. OB. Induced or Caesarean-section births are scheduled during the week whenever possible. (1) O Births occur with the same frequency on the different days of the week. Births occur with all different frequencies on the different days of the week. O At least two days have a different frequency of births than the other days. O At least one day has a different frequency of births than the other days. ( (2) O Births occur with all different frequencies on the different days of the week. At least two days have a different frequency of births than the other days. At least one day has a different frequency of births than the other days. O Births occur with the same frequency on the different days of the week
