At the end of each semester, Professor Mann calculates an overall score for each of his students in large sections of an Introductory Statistics course. The overall score is calculated based on each students performance on homework, attendance, tests, quizzes and a final exam. A final grade is then assigned based on the overall score for the course. In a particular semester, the scores are normally distributed with a mean score of l = 78 and a standard deviation o = 6. Professor Mann decides to give A to the top 14% of the students. What is the the minimum score a student can get and still get an A?
