That is, find the p th percentile for X. Go to Step 2.
WebApr 21, 2024 · First, we go the Z table and find the probability closest to 0.90 and determine what the corresponding Z score is. For any normal distribution a probability of 90% corresponds to a Z score of about 1.28. We also could have computed this using R by using the qnorm () function to find the Z score corresponding to a 90 percent probability.
