Step 1
We are given P(z > -1.24) = 0.8925. Since the standard normal distribution is symmetric around 0, we can find P(z < 1.24) = 0.8925. Show more…

For a standard normal distribution, find: P(z < -1.32)
69. Assume Z has a standard normal distribution: Use the "Z Table" to determine the value for z that solves each of the following: (a) P(Z < z) = 0.9 (b) P(Z < z) = 0.5 (c) P(Z > z) = 0.1 (d) P(Z > z) = 0.9 (e) P(-1.24 < Z < z) = 0.8
