Can a score of135 be described as average?”
What percentage of the population have a score of 130 or above?
What percentage of the population has a score below 130?

5. Using the Normal Curve
Scenario: You administer a test that is normally distributed with a mean of 100 and a standard deviation of 15.
What percentile rank is a score of 85?
What percentile rank is a score of 115?
What is a z-score of a score of 85?
What is a z-score of a score of 115?
What is a T-score of a score of 70?
