A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2771 occupants not wearing seat belts, 34 were killed. Among 7799 occupants wearing seat belts, 10 were killed. Use a 0.01 significance level to test the claim that seat belts are effective in reducing fatalities. Complete parts (a) hrough (c) below. . Test the claim using a hypothesis test. 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 he null and alternative hypotheses for the hypothesis test? DA. Ho: P1 = P2 H1: P1 # P2 O B. Ho: P1 +P2 H1: P1 = P2 O C. Ho: P1 = P2 H1: P, > P2 O D. Ho: P1 = P2 H1: P1 < P2 O E. Ho: P1SP2 H1: P1 # P2 OF. Ho: P12 P2 H1: P1 # P2
