A used car dealer says that the mean price of a three-year-old sports utility vehicle is $19,000. You suspect this claim is incorrect and find that a random sample of 23 similar vehicles has a mean price of $19,842 and a standard deviation of $1998. Is there enough evidence to reject the claim at a=0.05? Complete parts (a) through (e) below. Assume the population is normally distributed. O A. Ho: p2 $19,000 Hu<$19,000 OD. Ho p> $19,000 H: 5 $19,000 O B. Ho: H = $19,000 Hu> $19.000 O E. Ho: u* $19,000 Ha u = $19,000 C. Ho H = $19,000 H: 1*$19,000 OF HA = $19,000 H:<$19,000 (b) Find the critical value(s) and identify the rejection region(s). What is (are) the critical value(s), to? to =0 (Use a comma to separate answers as needed. Round to three decimal places as needed.)
