A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2756 occupants not wearing seat belts, 27 were killed. Among 7612 occupants wearing seat belts. 17 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. Identify the P-value P-value = 0 (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? reject the null hypothesis. There is sufficient evidence to support the claim that The P-value is less than the significance level of a = 0.05, so the fatality rate is higher for those not wearing seat belts. b. Test the claim by constructing an appropriate confidence interval. The appropriate confidence interval is < (P₁-P₂) < (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? Because the confidence interval limits include Because the confidence interval limits values, it appears that the fatality rate is c. What do the results suggest about the effectiveness of seat belts? H More Next 0, it appears that the two fatality rates are for those not wearing seat belts √i Vi 1,
