A criminologist developed a test to measure recidivism, where low scores indicated a lower probability of repeating the criminal behavior. It has an approximately normal distribution with a mean of 140 and a standard deviation of 40.

A. What is the z-score for a test score of 200? How would you interpret that z-score?

B. What is the percentile rank of a score of 172? How would you interpret that percentile rank?

C. What proportion of respondents should score between 140 and 195? How would you interpret that proportion?

Proportions (percentages) in a Z Distribution A large population of scores from a standardized test are normally distributed with a population mean (μ) of 50 and a standard deviation (σ) of 5. Because the scores are normally distributed, the whole population can be converted into a Z distribution. Because the Z distribution has symmetrical bell shape with known properties, it’s possible to mathematically figure out the percentage of scores within any specified area in the distribution. The Z table provides...
