WebI am trying to derive the covariance of two sample means and get confused at one point. Given is a sample of size n with paired dependent observations xi and yi as realizations of RVs X and Y and sample means ˉx and ˉy. I try to derive cov(ˉx, ˉy). I am relatively sure the result should be cov(ˉx, ˉy) = 1 ncov(X, Y) However I arrive at WebUse this statistical significance calculator to easily calculate the p-value and determine whether the difference between two proportions or means (independent groups) is …
