In a survey of 500 drivers from the South, 406 wear a seat belt. In a survey of 360 drivers from the Northeast, 289 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).
