In a survey of 1000 drivers from Region A, 849 wear a seat belt. In a survey of 1000 drivers from Region B, 908 wear a seat belt. At a =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. Complete parts (a) through (e) below.

Question
In a survey of 1000 drivers from Region A, 849 wear a seat belt. In a survey of 1000 drivers from Region B, 908 wear a seat belt. At a=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. Complete parts (a) through (e) below. (a) Identify the claim and state Ho and H. 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. A. The claim is that the proportion of drivers who wear seat belts in Region A is less than the proportion of drivers who wear seat belts Region B. O B. The claim is that the proportions of drivers who wear seat belts in both regions are equal. OC. The claim is that the proportion of drivers who wear seat belts in Region A is greater than the proportion of drivers who wear seat belts in Region B. O D. The claim is that the proportions of drivers who wear seat belts in both regions add up to 1. State H, and H. Choose the correct answer below. OA. Hg: P1 SP2 H: P, > P2 O D. Ho: P1> P2 H: P, SP2 C. Họ: P1 2 P2 H P, <P2 OF. Ho: P1 *P2 H P=P2 O B. Ho: P < P2 OE Ho: P =P2 H P, P2 (b) Find the critical value(s) and identify the rejection region(s). Select the correct choice below and fill in the answer boxes to complete your choice. O A. There are two critical values, zo =, and two rejection regions, z< and z>- (Use a comma to separate answers as needed. Round to two decimal places as needed.) O B. There is one critical value, zo =, and one rejection region, z>. (Round to two decimal places as needed.) OC. There is one critical value, zo=, and one rejection region, z<. (Round to two decimal places as needed.)
