A used car dealer says that the mean price of a three-year-old sports utility vehicle is $22,000. You suspect this claim is incorrect and find that a random sample of 20 similar vehicles has a mean price of $22,711 and a standard deviation of $1990. Is there enough evidence to reject the claim at a = 0.05? Complete parts (a) through (e) below. Assume the population is normally distributed. (d) Decide whether to reject or fail to reject the null hypothesis. OA. Fail to reject Ho because the test statistic is not in the rejection region(s). B. Reject Ho because the test statistic is in the rejection region(s). OC. Fail to reject Ho because the test statistic is in the rejection region(s). O D. Reject Ho because the test statistic is not in the rejection region(s).
