"Suppose that two populations have equal population variances but have different sizes: . Compare the variances of the sample means for a sample of size . Is it easier to approximate the mean of a smaller population?"

Where do I even begin? :(

Hey SC313.

What do the N's refer to? (Are you dealing with finite populations as opposed to infinite ones)? - January 31st 2013, 06:59 AMSC313Re: Comparing Variances of the Sample Means
