SOLVED: Let X1, X2, Xn be a sample and c be any nonzero constant. Show that if Y1 = X1 ε, Y2 = X2 c, ..., Yn = Xn ε, then s^2 = s^2. Show that if Y1 = cX1, Y2 = cX2, ..., Yn = cXn, then s^2 = c^2s^2 and Sy = |c|s: where s^2 is the sample variance of the X's and s^2 is the sample variance of the Y's.
