Question

​(c) Find the standardized test​ statistic, z.​(Round to two decimal places as​ needed.)

(d) Decide whether to reject or fail to reject the null

hypothesis.
​(e) Interpret the decision in the context of the original claim.
In a survey of 1000 drivers from Region A, 856 wear a seat belt. In a survey of 1000 drivers from Region B, 910 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. (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 is one critical value, zo = and one rejection region, z < (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.) O C. 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.)
