Students’ scores on a test in a public administration course follow a normal distribution with a mean of 150 points and a standard deviation of 12. One student who scored 161 on the test and received the grade of B is considering protesting his grade. He feels that the professor did not like him and awarded him a lower grade than his score deserved. The professor disagrees: She maintains that the top 10 percent of scores were given an A, the next 10 percent a B and so on—and that there was no discrimination. Based on the professor’s grading criteria, does the student have grounds for protest? Explain your answer.
