Webz) = .64, i.e. a z such that P(−z < Z < z) = .64. Because of the complement rule, this implies that P(Z < −z) +P(Z > z) = 1− .64 = .36, and, again since N(0,1) is symmetric, P(Z < −z) = P(Z > z). So, P(Z > z) must be equal to .36/2 = .18. Applying the comple-ment rule (again) and using the table we find that P(Z > z) = .18 ⇐⇒ 1− ...

In a normal distribution 50% of the population is greater than the mean (z=0); an additional 45.91% is between the mean and z=-1.74. Therefore, the percent of the population below z=-1.74 must be 4.09%. . Upvote • 0 Downvote. fishing ship in jesus\u0027 time clipart
