![(c) Find the standardized test statistic t.
t = _______ (Round to two decimal places as needed.)
(d) Decide whether to reject or fail to reject the null hypothesis.
- O A. Reject H₀ because the test statistic is not in the rejection region(s).
- O B. Fail to reject H₀ because the test statistic is not in the rejection region(s).
- O C. Fail to reject H₀ because the test statistic is in the rejection region(s).
- O D. Reject H₀ because the test statistic is in the rejection region(s).
(e) Interpret the decision in the context of the original claim.
- O A. At the 1% level of significance, there is sufficient evidence to reject the claim that the mean price is $19,000.
- O B. At the 1% level of significance, there is not sufficient evidence to reject the claim that the mean price is $19,000.
- O C. At the 1% level of significance, there is sufficient evidence to reject the claim that the mean price is not $19,000.
- O D. At the 1% level of significance, there is not sufficient evidence to reject the claim that the mean price is not $19,000.

![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 $19,585 and a standard deviation of $1910. Is there enough evidence to reject the claim at an α = 0.01? Complete parts (a) through (e).
(a) Write the claim mathematically and identify H₀ and H₁.
Which of the following correctly states H₀ and H₁?
A. H₀: µ = $19,000
H₁: µ ≠ $19,000
B. H₀: µ ≠ $19,000
H₁: µ = $19,000
C. H₀: µ ≤ $19,000
H₁: µ > $19,000
D. H₀: µ < $19,000
H₁: µ = $19,000
E. H₀: µ ≥ $19,000
H₁: µ = $19,000
F. H₀: µ = $19,000
H₁: µ > $19,000
(b) Find the critical value(s) and identify the rejection region(s). What is(are) the critical value(s), t₀?

A. Reject H₀ because the test statistic is not in the rejection region(s).
B. Fail to reject H₀ because the test statistic is not in the rejection region(s).
C. Fail to reject H₀ because the test statistic is in the rejection region(s).
