(b) Verify that the requirements for performing a chi-square test of independence are satisfied. Select all requirements for a chi-square test of independence. A. All expected frequencies are greater than or equal to 1. B. No more than 20% of the expected frequencies are less than 5. c. All expected frequencies are greater than or equal to 5. D. All expected frequencies are greater than or equal to 10. E. The expected frequencies are approximately Normal (c) Test whether family structure and sexual activity of 15- to 19-year-old females are independent at the a = 0.05 level of significance. State the hypotheses. Choose the correct answer below. O A. Ho: Sexual activity and family structure are independent. Hy: Sexual activity and family structure are dependent. O B.

Hy: Sexual activity and family structure are independent. O C. Ho: H1 = E2 and H3 = Eg and H3 = Eg and H4 = E4 Hy: At least one mean is different from what is expected. O D. Ho: P1 = P2 = P3 = P4 H, : At least one proportion is different from the others. (d) Compute the chi-square test statistic. x3 =(Round to three decimal places as needed.) Determine the P-value. P-value = (Round to three decimal places as needed.) Make the proper conclusion. Choose the correct answer below. O A. The P-value is greater than a, so do not reject Ho. There is not sufficient evidence at the a = 0.05 level of significance to conclude that sexual activity and family structure are related. O B. The P-value is less than a, so do not reject Ho. There is not sufficient evidence at the a = 0.05 level of significance to conclude that sexual activity and family structure are related. O C. The P-value is less than a, so reject Ho. There is sufficient evidence at the a = 0.05 level of significance to conclude that sexual activity and family structure are related O D. The P-value is greater than a, so reject Ho. There is sufficient evidence at the a= 0.05 level of significance to conclude that sexual activity and family structure are related.
