Random variable z follows the standard normal distribution. In each of the following, sketch the standard normal distribution to illustrate your result. Use 4 decimal places. (a)[3] Find P(-3.0 ≤z ≤ 3.0). (b)[2] Find P(Z > 1.0). Hint: Use some Excel lookups: ZV NORM.S.DIST(zv,1) -3.00 0.0013 -2.00 0.0228 -1.00 0.1587 2.00 0.9772 3.00 0.9987 Random variable z follows the standard normal distribution.
