Last updated: 7/20/2022

Use the normal distribution of SAT critical reading scores for which the mean is 514 and the standard deviation is 109. Assume the variable x is normally distributed. (a) What percent of the SAT verbal scores are less than 600? (b) If 1000 SAT verbal scores are randomly selected, about how many would you expect to be greater than 550?
