Chapter 1, Problem 78(choose chapter or problem)
Consider a sample x1, x2,, xn and suppose that thevalues of x, s2, and s have been calculated.a. Let yi = xi 2 x for i = 1,, n. How do the values ofs2 and s for the yis compare to the correspondingvalues for the xis? Explain.b. Let zi = (xi 2 x)ys for i = 1,, n. What are thevalues of the sample variance and sample standarddeviation for the zis?
