A teacher gives a test to a large group of students. The results are closely approximated by a normal curve. The mean is 77 with a standard deviation of 4. The teacher wishes to give A's to the top 7% of the students and F's to the bottom 7%. A grade of B is given to the next 14%, with D's given similarly. All other students get C's. Find the bottom cutoff for a D.
