1. Consider a sample x1,...,xn from some statistical population, and let and S2 denote the sample mean and sample variance. a. Suppose new data are created, y,..., Yn, where y = c1 + x; where c is a known constant. Show that = c+ and S = = b. Suppose new data are created, y, ..., Yn, where y = C2x; where c is a known constant. Show that y C2 and S = 2S22. Note: Combining the results in parts a and b shows that if y = C + Cxi, then y = c + c and S = cS. C+
