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.
