(See Steps) points Using a test for paired data, test the claim about the mean of the difference of the two populations at the given level of significance
Question:
10 points Using a test for paired data, test the claim about the mean of the difference of the two populations at the given level of significance α = 0.01 using the given statistics. Assume the populations are normally distributed, and that the population variances are unequal.
Claim: μd < 0, α = 0.01. Sample statistics:
d(bar) = 3.2, sd = 1.38, n1 = 25
