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).
