K A used car dealer says that the mean price of a three-year-old sports utility vehicle is $20,000. You suspect this claim is incorrect and find that a random sample of 20 similar vehicles has a mean price of $20,682 and a standard deviation of $1943. Is there enough evidence to reject the claim at = 0.05? Complete parts (a) through (e) below. Assume the population is normally distributed. (c) Find the standardized test statistic t t= = (Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. OA. Reject Ho because the test statistic is not in the rejection region(s). OB. Fail to reject Ho because the test statistic is in the rejection region(s). OC. Reject Ho because the test statistic is in the rejection region(s). D. Fail to reject Ho because the test statistic is not in the rejection region(s). (e) Interpret the decision in the context of the original claim. OA. At the 5% level of significance, there is not sufficient evidence to reject the claim that the mean price is $20,000. OR At the 5% level of significance there is sufficient evidence to reject the claim that the mean nrice is not 0 i R (0,0) TC More K A used car dealer says that the mean price of a three-year-old sports utility vehicle is $20,000.
