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 Number of Births Sun 38 Mon Tues Wed 60 Thurs 59 Fri Sat 57 64 56 Determine the null and alternative hypotheses. Calculate the test statistic, 2=Round to three decimal places as needed) Calculate the P-value. P-value =O (Round to four decimal places as needed) What is the conclusion for this hypothesis test? O A. Fail to reject Hg. 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 Hg. There is sufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week. OC. Reject Hg. 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 Hg. 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. OB. Induced or Caesarean-section births are scheduled on weekends whenever possible.

Question

I am having some trouble working this problem out and some help would be appriciated, please and thank you.

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 Fri Sat Number of Births 38 57 64 60 59 56 42 Determine the null and alternative hypotheses. Ho: H,: Calculate the test statistic, y 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. Fail to reject H,. 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 H. There is sufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week. OC. Reject H,. 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 Hn. 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.

Determine the null and alternative hypotheses. Ho: Calc x2 = At least one day has a different frequency of births than the other days. Calc At least two days have a different frequency of births than the other days. P-va Births occur with the same frequency on the different days of the week. Wha Births occur with all different frequencies on the different days of the week.
