Hello. I was looking at some practice problems in my textbook, and I was puzzled about how to attempt the following question. Any help would be very much appreciated!
The two-sample t-statistic is defined as
where Sp = sqrt[((m+1)Sx^2 + (n+1)Sy^2) divided by (m+n-2)].
Express t in terms of T1 =
, T = , and T* = .Correction above: It should be (m-1) and (n-1) in the numerator of the fraction underneath the square root for the expression for Sp and not (m+1) and (n+1)
