A sociologist randomly selects 378 females 15 to 19 years old and asks each to disclose her family structure at age 14 and whether she has had sexual intercourse. Use the results in the accompanying table to complete parts (a) through (f) below. Click here to view the data table of family structure and sexual activity." Click here to view the Chi-Square table of critical values. (a) Compute the expected values of each cell under the assumption of independence. Had sexual intercourse Both Biological or Adoptive Parents Single Parent Parent and Stepparent Non-parental Guardian 60 3 63 Yes 16 85 No (Round to two decimal places as needed.) (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. No more than 20% of the expected frequencies are less than 5. OB. All expected frequencies are greater than or equal to 5. [ C. All expected frequencies are greater than or equal to 10. D. All expected frequencies are greater than or equal to 1. E. The expected frequencies are approximately Normal. (c) Compute the chi-square test statistic. x 2 : (Round to three decimal places as needed.) (d) Test whether family structure and sexual activity of 15- to 19-year-old females are independent at the a = 0.1 level of significance. State the hypotheses. Choose the correct answer below. O A. Ho: Sexual activity and the family structure are independent. H: Sexual activity and the family structure are dependent. O B. Ho: P1 = P2 = P3 = P4 Hy : At least one proportion is different from the others. O C. Ho: H1 = E, and #4 = E4 and #3 = E3 and #4 = E4 Hy : At least one mean is different from what is expected. What range of P-values does the test statistic correspond to? The P-value is (1) _ Make the proper conclusion. Choose the correct answer below. O A. The P-value is less than a, so reject Ho- There is sufficient evidence at the
