You are looking at Chabot's class schedule, trying to decide who to take for Math 43. Suppose that one of the professor's teaching the class has a policy of giving A's to the top 15% of the scores on her final, regardless of the actual scores. Further suppose that the distribution of scores on her final is approximately normal with mean 71 and standard deviation 9. What score would you need to earn an A?
