Answer: 0.8433 Probability & Std. Norm. Dist. Let x have a normal distribution with = 13 and = 3. Find the probability that an x value selected at random from this distribution is between 8 and 16. P(8 x 16) P(1.67 z 1) P (z 1) P (z 1.67) 0.8413  0.0475 Answer: 0.7938 Example Find z such that 81% of the area under the standard normal curve lies between z and z . Answer: 1.31 Example Find z so that 3.5% of the standard normal curve lies to the right of z . Answer: 1.81...
