Question
Test the claim about the difference between two population means , and u, at the level of significance a. Assume the samples are random and independent, and
the populations are normally distributed.
Claim: μ μ2 α- 0.01
Population statistics: o, = 3.5, o2 = 1.4
Sample statistics: x, = 17, n, = 31, x2 = 15, n2 = 30
Determine the P-value.
P-value = 0.003 (Round to three decimal places as needed.)
What is the proper decision?
O A. Reject Ho. There is not enough evidence at the 1% level of significance to reject the claim.
O B. Reject Ho. There is enough evidence at the 1% level of significance to reject the claim.
OC. Fail to reject Ho. There is enough evidence at the 1% level of significance to reject the claim.
O D. Fail to reject Ho. There is not enough evidence at the 1% level of significance to reject the claim.
