Question: The expected distribution on an exam roughly follows a normal curve in which the highest scoring 2.5% of the students get A’s; the next highest scoring 14%, B’s; the next 67% C’s; the next 14% D’s; and the lowest 2.5% F’s. A class takes a test using a new grading system and 10 get A’s; 34 get B’s; 140 get C’s; 10 get D’s; and 6 get F’s. Can you conclude that the new system produces a different distribution of grades? Use \(\alpha \) = .01.
