Question

In a survey of 1000 drivers from Region​ A, 867 wear a seat belt. In a survey of 1000 drivers from Region​ B, 923 wear a seat belt. At α=0.10, is there evidence to support the claim that the proportion of drivers who wear seat belts in Region A is less than the proportion of drivers who wear seat belts in Region​ B? Assume that the samples are random and independent.

Identify the claim. Let population 1 be drivers from Region A and let population 2 be drivers from Region B. Choose the correct answer below.

State H0 and Ha

Find the critical​ value(s) and identify the rejection​ region(s).

Find the standardized test statistic, z.

Decide whether to reject or fail to reject the null hypothesis.

Interpret the decision in the context of the original claim.
