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 22 similar vehicles has a mean price of $20,858 and a standard deviation of $1900. Is there enough evidence to reject the claim at a = 0.05? Complete parts (a) through (e) below. Assume the population is normally distributed. I Which of the following correctly states Ho and H₂? A. Ho: H=$20,000 H₂: μ#$20,000 O D. Ho: μ>$20,000 H₂H<$20,000 (…) O B. Ho: μ# $20,000 H₂: H=$20,000 O E. Ho: μ = $20,000 H₂: μ>$20,000 (b) Find the critical value(s) and identify the rejection region(s). What is (are) the critical value(s), to? to = (Use a comma to separate answers as needed. Round to three decimal places as needed.) OC. Ho: >$20,000 H₂: ≤ $20,000 OF. Ho: μ = $20,000 H,:μ < $20.000
