First define the null and alternative hypotheses.
Ho
H₁:
Calculate the test statistic.
T=
Calculate the critical value.
The critical value is
What is the conclusion for this hypothesis test?
O A. Fail to reject Ho. There is insufficient evidence to warrant rejection of the claim of no difference.
OB. Reject Ho. There is insufficient evidence to warrant rejection of the claim of no difference.
O C. Reject Ho. There is sufficient evidence to warrant rejection of the claim of no difference.
O D. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim of no difference.
