- The scores on a certain test are normally distributed with mean μ = 82 and standard deviation σ = 8. What is the probability that a given student scores less than 84 on the test? Step 1: Find the z-score. First, we will find the z-score associated with a score of 84: z-score = (x – μ) / σ = (84 – 82) / 8 = 2 / 8 = 0.25 Step 2: Us… See more
