Test the claim about the difference between two population means mu 1 and mu 2 at the level of significance alpha. Assume the samples are random and independent, and the populations are normally distributed. Claim: mu 1equalsmu 2; alphaequals0.10. Assume sigma Subscript 1 Superscript 2equalssigma Subscript 2 Superscript 2 Sample statistics: x overbar 1equals30.1, s 1equals3.5, n 1equals13 and x overbar 2equals32.9, s 2equals2.4, n 2equals15
