A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2927 occupants not wearing seat belts, 39 were killed. Among 7702 occupants wearing seat belts, 11 were killed. Use a 0.05 significance level to test the claim that seat belts are effective in reducing fatalities. Complete parts (a) through (c) below. Consider the first sample to be the sample of occupants not wearing seat belts and the second sample to be the sample of occupants wearing seat belts. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: P1 = P2 O B. Ho: P1 S P2 O C. Ho: P1 = P2 H1: P1 > P2 H1 : P1 # P2 H1 : P1 # P2 O D. Ho: P1 2 P2 O E. Ho: P1 = P2 OF. Ho: P1 # P2 H1 : P1 # P2 Hy: P1
