A used car dealer says that the mean price of a three-year-old sports utility vehicle is $23,000. You suspect this claim is incorrect and find that a random sample of 21 similar vehidles has a mean price of $23,626 and a standard deviation of$1978. Is there enough evidence to reject the claim at a = 0.01? Complete parts (a) through (e) below. Assume the population is normally distributed.(a) Write the claim mathematically and identify Ho and H,Which of the following correctly states Ho and H, ?O A. Ho: u#$23,000H:u= $23,000O B. Ho: = $23,000H:u<$23,000c. Hạ: u= $23,000H u# $23,000O D. Ho: u2 $23,000H:u<$23,000O E. Ho: u> $23,000H: us $23,000OF. Ho: u= $23,000Hp> $23,000(b) Find the critical value(s) and identify the rejection region(s).What is(are) the critical value(s), to?to- -2.845,2.845(Use a comma to separate answers as needed.
