A used car dealer says that the mean price of a three-year-old sports utility vehicle is $21,000. You suspect this claim is incorrect and find that a random sample of 22 similar vehicles has a mean price of $21,742 and a standard deviation of $1922. Is there enough evidence to reject the claim at a = 0.01? Complete parts (a) through (e) below. Assume the population is normally distributed. O A. Ho: H> $21,000 O B. Ho: H #$21,000 O C. Ho: H = $21,000 Ha: ps $21,000 Ha: p= $21,000 Ha: H# $21,000 O D. Ho: H= $21,000 O E. Ho: H= $21,000 OF. Ho: H > $21,000 Ha: p $21,000 Ha: H O B. (> X + More Time Remaining: 00:51:12 Next
