Suppose that Z is the standard normal distribution. Find P(Z<-1.81).
Suppose that Z is the standard normal distribution. Find P(Z>2).
Suppose that Z is the standard normal distribution. Find P(-1.95<Z<1.07).
Suppose that Z is the standard normal distribution. What value of Z represents the 20th percentile?
Solution :
P(Z < -1.81) = 0.0351
P(Z > 2) = 1 - P(Z < 2) = 1 - 0.9772 = 0.0228
P(-1.95 < Z < 1.07) = P(Z < 1.07) - P(Z < -1.95) = 0.8321
P(Z < -0.84) = 0.20
20th percentile = -0.84

Standard Normal distribution. With regards to a standard normal distribution complete the following: (a) Find P(Z > 0), the proportion of the standard normal distribution above the z-score of 0. (b) Find P(Z <-0.75), the proportion of the standard normal distribution below the Z-score of -0.75 (c) Find P(-1.15<z <2.04). (d) Find P(Z > -1.25). (e) Find the Z-score corresponding to Pso, the 90th percentile value.
