SOLVED: Random samples are taken from two independent normal populations and the following statistics are obtained:Sample 1: n = 7, xÌ„ = 50.92, sâ‚ = 27.74Sample 2: n = 81, xÌ„ = 54.20, sâ‚‚ = 34.49At the 0.05 significance level, is there evidence suggesting that the mean of population 2 is greater than the mean of population 1? At the 0.05 significance level, test the hypothesis that the standard deviations of the two populations are equal.

SOLVED: Random samples are taken from two independent normal populations and the following statistics are obtained:Sample 1: n = 7, xÌ„ = 50.92, sâ‚ = 27.74Sample 2:
