in a study done on a random sample of front seat occupants involved in a car crashes resulted in some interestinv facts discovered. among 2843 were not wearing seat belts 31 were killed. among 7765 occupants wearing seat-belt 44 were killed.

we want to test the claim that more death results in cases where occupants do not wear seat-belt.

use 0.10 significance level

Expert Solution

1 : not wearing belt

2 : wearing belt

alternate hypothesis = claim = p1 > p2

therefore,

conclusion : more death results in cases where occupants do not wear seat-belt (p1 > p2)

(please UPVOTE)

A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2500 occupants not wearing seat belts, 15 were killed. Among 7500 occupants wearing seat belts, 15 were killed. Use this data with 0.05 significance level to test the claim that the fatality rate is higher for those not wearing seat belts. (Write all necessary steps like Hypotheses, Test Statistic, P-value & Conclusion) Given that P(z<3.17)=0.9992.
