A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2965 occupants not wearing seat belts, 36 were killed. Among 7852 occupants wearing seat belts, 12 were killed Use a 0.01 significance level to test the claim that seat belts are offective in reducing fatalities 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.

A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2965 occupants not wearing seat belts, 36 were killed. Among 7852 occupants wearing seat belts 12 were killed. Use a 0.01 significance level to test the claim that seat belts are effective in reducing fatalises. Complete parts (a) through (c) below. identify the P-value. P-value (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? the significance level of a -0.01, so The P-value is bolls 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? the null hypothesis. There sufficient evidence to support the claim that the fatality rate is higher for those not wearing a
VE DONANT UN BEU-seur occupants involved in car crashes is obtained. Among 2965 occupants not weaning seat belts, 36 were killed. Among 7852 occupants wearing seat belts, 12 were kilde 0.01 significance level to test the claim that seat belts are effective in reducing fatalities. Complete parts (a) through (c) below. 145 (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? Because the confidence interval limits fatality rate is for those not wearing seat belts c. What do the results suggest about the effectiveness of seat belts? 0, it appears that the two fatality rates are CEETES Bocause the confidence interval limits include QA. The results suggest that the use of seat belts is associated with lower fatality rates than not using seat belts OB. The results suggest that the use of soat bolts is associated with higher fatality rates than not using seat belts. OC. The results suggest that the use of seat belts is associated with the same fatality rates as not using seat belts OD. The results are inconclusive. valuse, it appears that the
