(a) Write the claim mathematically and identify Ho and H, Which of the following correctly states Ho and H,? OA. Ho u = $20,000 H > 520,000 OD. Ho -> $20,000 HA HS $20,000 O B. Ho u = $20,000 H, #

1.729 OD. (c) Find the standardized test statistic t. t= 1.61 (Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. X A. Fail to reject H, because the test statistic is in the rejection region(s) B. Fail to reject H, because the test statistic is not in the rejection region(s) OC. Reject H, because the test statistic is in the rejection region(s). OD. Reject He because the test statistic is not in the rejection region(s) (e) Interpret the decision in the context of the original claim. O A. At the 10% level of significance, there is not sufficient evidence to reject the claim that the mean price is not $20,000 B. At the 10% level of significance, there is sufficient evidence to reject the claim that the mean price is $20,000 OC. At the 10% level of significance, there is sufficiebt evidence to reject the claim that the mean price is not $20,000 OD. At the 10% level of significance, there is not sufficient evidence to reject the claim that the mean price is $20,000 Aused 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 21 similar vehides has a mean price of $20,886 and a standard deviation of 51949. Is there enough evidence to reject the claim ata=0.10? Complete parts (a) through (e) below. Assume the population is normally distributed (al Arite the claim mathematically and antifur Hand
