WebOct 23, 2024 · To find the probability of SAT scores in your sample exceeding 1380, you first find the z -score. The mean of our distribution is 1150, and the standard deviation is 150. The z -score tells you how many standard deviations away 1380 is from the mean. For a z -score of 1.53, the p -value is 0.937.
