It was found that in a study of air-bag effectiveness 900 crashes of midsize cars equipped with air bags, 70 of the crashes resulted in hospitalization of the drivers. We want to test the claim that the air-bag hospitalization rate is more that the 6.8% rate for crashes of midsize cars equipped with automatic safetly belts. At 0.05 significance level we conclude that there is sufficient evidence to support the claim that for crashes of midsize cars, the air-bag hospitalization rate exeeds the 6.8% rate for automatic safetly belts. Othere is no sufficient evidence to support the claim that for crashes of midsize cars, the air-bag hospitalization rate exceeds the 6.8% rate for automatic safetly belts. Othere is sufficient evidence to support the claim that for crashes of midsize cars, the air-bag hospitalization rate is at least 6.8% rate for automatic safetly belts. Othere is no sufficient evidence to support the claim that for crashes of midsize cars, the air-bag hospitalization rate is at least 6.8% rate for automatic safetly belts.

QUESTION 23
It was found that in a study of air-bag effectiveness 900 crashes of midsize cars equipped with air bags, 70 of the crashes resulted in hospitalization of the
drivers. We want to test the claim that the air-bag hospitalization rate is more that the 6.8% rate for crashes of midsize cars equipped with automatic
safetly belts. At 0.05 significance level we conclude that
Othere is sufficient evidence to support the claim that for crashes of midsize cars, the air-bag hospitalization rate exeeds the 6.8% rate for automatic
safetly belts.
there is no sufficient evidence to support the claim that for crashes of midsize cars, the air-bag hospitalization rate exceeds the 6.8% rate for automatic
safetly belts.
Othere is sufficient evidence to support the claim that for crashes of midsize cars, the air-bag hospitalization rate is at least 6.8% rate for automatic safetly
belts.
there is no sufficient evidence to support the claim that for crashes of midsize cars, the air-bag hospitalization rate is at least 6.8% rate for automatic
safetly belts.
