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 24 similar vehicles has a mean price of $20,899 and a standard deviation of $1926. Is there enough evidence to reject the claim at a = 0.10? Complete parts (a) through (e) below. Assume the population is normally distributed. (a) Write the claim mathematically and identify Ho and Ha- Which of the following correctly states Ho and Ha? O A. Ho: H = $20,000 O B. Ho: H > $20,000 O C. Ho: H # $20,000 Ha : u $20,000 Ha: H O C. t> OD.
