Question
Use a t-test to test the claim about the population mean u at the given level of significance oa using the given sample statistics. Assume the population is normally distributed.
Claim: u =51,100; a = 0.05 Sample statistics: x = 51,531, s = 2200, n = 18

What are the null and alternative hypotheses? Choose the correct answer below.
O A. Ho: H= 51,100
H: H#51,100
O B. Ho: H251,100
Hiu<51,100
OC. Ho: Hs51,100
H:> 51,100
O D. Ho: H#51,100
Hi H = 51,100
What is the value of the standardized test statistic?
The standardized test statistic, t is
(Round to two decimal places as needed.)
What is(are) the critical value(s)?
Hint:
left-tailed (<) , use "One Tail, a" column with a negative sign
right-tailed (>), use "One Tail, a" column with a positive sign
two-tailed (#), use "Two Tails, a" column with a negative and a positive sign.
The critical values are:
(Round to three decimal places as needed. Use a comma to separate answers as needed.)
Decide whether to reject or fail to reject the null hypothesis. Compare t with the critical values. See formula sheet for more details.
O A. Fail to reject Ho. There is enough evidence to reject the claim.
O B. Fail to reject Ho. There is not enough evidence to reject the claim.
O C. Reject Ho. There is enough evidence to reject the claim.
O D. Reject Ho. There is not enough evidence to reject the claim.
