Question

Perform a Goodness of Fit Using Numerical Data 01b Randomly selected birth records wereâ€< 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. Day Number of Births Sun 36 Mon 55 Tues 60 Wed 62 Thurs 63 Fri 62 Sat 49 Choose ALL correct statements from those given below. Answer 1. Ho: Births occur with the same frequency on the different days of the week. Hy: At least one day has a different frequency of births than the other days. 2. O Ho: At least one day has a different frequency of births than the other days. Hy: Births occur with the same frequency on the different days of the week. 3. O 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. 4. O P-value = 0.1032 5. O x2 = 10.553
