In a survey of 1005 adult Americans, 46% indicated that they were somewhat interested or very interested in having web access in their cars (USA TODAY, may 1, 2009). Suppose that the marketing manager of a car manufacturer claims that the 46% is based only on a sample and that 46% is close to half, so there is no reason to believe that the proportion of all adult Americans who want car web access is less than 0.50. Is the marketing manager correct in his claim? Provide statistical evidence to support your answer. For the purposes of this problem, assume that the sample can be considered representative of adult Americans. SO
