Find z value given probability excel
WebOct 16, 2024 · You can use the Standard Normal distribution table; find the probability 0.75 in the body of the table, and determine what z score corresponds to that. Then use z = (X-μ) / σ to solve for X. Mu (μ) is the mean; sigma (σ) is the standard deviation. 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.
