Extracted text: 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 24 similar vehicles has a mean price of $21,719 and a standard deviation of $1996. Is there enough evidence to reject the claim at a = 0.01? Complete parts (a) through (e) below. Assume the population is normally distributed. e (a) Write the claim mathematically and identify Ho and Ha. E1 Which of the following correctly states Ho and H,? O A.
