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. WebNov 5, 2024 · Using the full z table, we find that for a z score of 1.53, the p value is 0.937. This is the probability of SAT scores being 1380 or less (93.7%), and it’s the area under the curve left of the shaded area. To find the shaded area, you take away 0.937 from 1, which is the total area under the curve. Probability of x > 1380 = 1 − 0.937 = 0.063
