A teacher wishes to give A’s to the top 8% of the students and F’s to the bottom 8%. The next 10% will be B’s and D’s, and the rest receive C’s. The scores are normally distributed with a mean of 78 and a standard deviation of 8. Use the data to find the bottom cut-off for a D grade.
Sally had a z score of +0.25 on a test with a mean of 62 and a standard deviation of 5. What was her raw score on the test?
Claire earned a score of 96 on Exam A that had a mean of 100 and a standard deviation of 10. She is about to take Exam B that has a mean of 600 and a standard deviation of 50.
