Please read "Notes on Summation Operator" posted on the course website. Compute the sum 1xi, the average = (1/n), and the sample variance (1/(n 1)) (xi) when n = 5 and x = i, i.e., x = 1, x2 = 2, x3 = 3, x4 = 4, x5 = 5 as follows. (a) Compute xi x n i=1 (b) Compute = (1/n) 1 xi 1 (c) Compute s = (1/(n 1)) 1 (xi x) - 1(xi x) (d) Show that (x) = 0 for this example. (e) Show that (xi) = 0 holds for any sequence of numbers {x} given that x = (1/n) in i=1 xi.
