Question
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 20 similar vehicles has a mean price of $20,641 and a standard deviation of $1963. 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 H, ? O A. Ho: u2 $20,000 H:p< $20,000 O B. Ho: u>$20,000 H: us $20,000 OC.
