Looking at the data for the results of a test, a student saw that his z-score was 2.5 with a mean of 79 and the standard deviation of 6. What was his actual test score?

Help me find the test score please!

Answer 1

z score of 2.5 means the actual test score is 2.5 standard deviations above the mean, or 79 + 2.5 * 6 = 94.
