Answer These questions D and E
![A used car dealer says that the mean price of a three-year-old sports utility vehicle is $23,000. You suspect the claim is incorrect and find that a random sample of 22 similar vehicles has a mean price of $23,691 and a standard deviation of $1911. Is there enough evidence to reject the claim at \(\alpha = 0.01\)? Complete parts (a) through (e) below. Assume the population is normally distributed.
