The z-score that corresponds to p80
WebFull text: A score that is 15 points below the mean corresponds to a z-score of -1.8. What is the. standard deviation? The question doesn't give the mean, do you have any suggestions on how I should tackle this? So far I have: (mean-15) - mean / standard deviation = -1.8 z-score. To help preserve questions and answers, this is an automated copy ... WebUse the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries,use the Z-score halfway between the corresponding Z-scores.

WebAug 30, 2024 · Suppose we would like to find the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1. First, we will look up the value 0.4 in the z-table: Then, we will look up the value 1 in the z-table: Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859.
