Question
Test the claim about the difference between two population means u, and u, at the level of significance a. Assume the samples are random and independent, and the populations are normally distributed.
Claim: µ, =H2; a = 0.01
Population statistics: o, = 3.4, o2 =1.7
Sample statistics: X, = 15, n, = 27, X2 = 17, n2 = 30
Determine the alternative hypothesis.
Ha: H1
H2
Determine the standardized test statistic.
(Round to two decimal places as needed.)
Determine the P-value.
P-value = (Round to three decimal places as needed.)
What is the proper decision?

Test the claim about the difference between two population means u, and u2 at the level of significance a. Assume the samples are random and independent, and the populations are normally distributed.
Claim: 4, =H2; a = 0.01
Population statistics: o, = 3.4, o2 = 1.7

(Round to three decimal places as needed.)
What is the proper decision?
O A. Fail to reject Ho. There is not enough evidence at the 1% level of significance to reject the claim.
O B. Fail to reject Hn. There is enough evidence at the 1% level of significance to reject the claim.
O C. Reject Ho. There is not enough evidence at the 1% level of significance to reject the claim.
O D. Reject Ho. There is enough evidence at the 1% level of significance to reject the claim.
