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 randon sample of 24 similar vehicles has a mean price of $21,773 and a standard deviation of $1996. 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 H. Which of the following correctly states H, and H ?
