Question

Transcribed Image Text: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?

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. Induced or Caesarean-section births are scheduled during the week whenever possible.
