A simple random sample of front seat occupants involved in car crashes is obtained. Among 2780 occupants not wearing seat belts, 37 were killed. Among 7731 occupants wearing seat belts, 15 were killed. Use a 0.05 significance level to test the claim that seat belts are effective in reducing fatalities. (a) Test the claim using a hypothesis test. Ho: P1 = P2 H1: Choose one of the following letter_ A: P1 = P2; B: P1 > P2; C: P1 < P2 D: P1 # p2 (b) Identify the test statistic. z test = 7.33 (Round to two decimal places.) (c) Identify the P-value. Conclusion p-value is 0.000 (Round to three decimal places.) since p-value is [ less than , or greater than) s.f.0.05 so Reject (Reject / Fail to reiect)
