A used car dealer says that the mean price of a three-year-old sports utility vehicle is $19,000. You suspect this claim is incorrect and find that a random sample of 23 similar vehicles has a mean price of $19,586 and a standard deviation of $1910. Is there enough evidence to reject the claim at a= 001? Complete p

(a) Write the claim mathematically and identify H, and Ha-
Which of the following correctly states Ho and H,?
O A. Hg: =$19,000
