In a survey of 460 drivers from the South, 414 wear a seat belt. In a survey of 370 drivers from the Northeast, 290 wear a seat belt. At a = 0.06, can you support the claim that the proportion of drivers who wear seat belts is greater in the South than in the Northeast? Assume the random samples are independent. Complete parts (a) through (e). OC. z< O D. 7> (c) Find the standardized test statistic. z= (Round to two decimal places as needed.) (d) Decide whether reject or fail to reject the null hypothesis. Choose the correct answer below. O Fail to reject Ho because the test statistic is in the rejection region. O Fail to reject Ho because the test statistic is not in the rejection region. O Reject Ho because the test statistic is in the rejection region. O Reject Ho because the test statistic is not in the rejection region. (e) Interpret the decision in the context of the original claim. Choose the correct answer below. O A. At the 6% significance level, there is insufficient evidence to support the claim. O B. At the 6% significance level, there is insufficient evidence to reject the claim. OC. At the 6% significance level, there is sufficient evidence to support the claim.
