Question
Randomly selected birth records were obtained, and cateqorized 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 Mon 63 Tues Wed Thurs Fri 46 Sat 58 59 63 63 36 Determine the null and alternative hypotheses. Ho H, Calc At least one day has a different frequency of births than the other days. At least two days have a different frequency of births than the other days. Calc P-va Births occur with all different frequencies on the different days of the week. Wha Births occur with the same frequency on the different days of the week. O A. 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 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. 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 insufficient 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. O B.
