Professor stickler always grades on the curve yes i see to, Ask an Expert

Statistics

Professor Stickler always grades "on the curve." "Yes, I see to it that my grades are distributed as 7 percent A's, 24 percent B's, 38 percent C's, 24 percent D's, and 7 percent flunks," he explained to a young colleague.

The colleague, convinced that the professor is really a softer touch than he sounds, looked at Professor Stickler's grade distribution for the past year. He found frequencies of 20, 74, 120, 88, and 38, respectively, for the five categories, A through F. Perform a x² test for the colleague. What do you conclude about Professor Stickler?
