[R] Compraring two independent samples

Hi, In my reading of pairing means of two independent samples, I read statements such as the standard error of the meanof X1 minus the mean of X2 is the square root of s1^2/n1+s2^2/n2. Then I read: We could now derive the two independent samples confidence interval and test statistic. However, a
