A simple random sample of front seat occupants involved in car crashes is obtained. Among 2895 occupants not wearing seat belts. 35 were killed. Among 7861 occupants wearing seat belts, 20 were killed Use a 0.05 significance level to test the claim that seat belts are effective in reducing tataises. Complete parts (a) through (c) below a. 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 the null and alternative hypotheses for the hypothesis est? OF OA H₂ Pt Spy H₂ D₂ D₂ OD. HjDjPj H₂ Di PP HAPP H₁: Dy*P₂ OE My Py*P H₁ PyP OC. Hy Py*P₂ Hy: Dy Dy OF H₂Py*P₂ Hi Py*P₂

b. Test the claim by constructing an appropriate confidence interval The appropriate confidence intervals (Round to three decimal places as needed.)

What do the results suggest about the effectiveness 0, it appears that the two fatality rates are the claim that the fatality rate is higher for those not wearing a bas Because the confidence interval limits include of seat belts? OA. The results suggest that the use of seat bets is associated with lower fatality rates than not using seat belts OB. The results suggest that the use of seat belts is associated with the same fatality rates as not using seat belts OC. The results suggest that the use of seat belts is associated with higher fatality rates than not using seat belts. OD. The results are inconclusive values, it appears that the fatality rate is br Pose
