What are the null and alternative hypotheses? Choose the correct answer below.
Ο Α. Η μ= 51,100
Ha: µ#51,100
B. H μ251,100
Ha: µ<51,100
C. Ho: µ#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.
A. Fail to reject Ho. There is enough evidence to reject the claim.
B. Reject Ho. There is enough evidence to reject the claim.
C. Reject Ho. There is not enough evidence to reject the claim.
D. Fail to reject Ho. There is not enough evidence to reject the claim.
