Suppose that you take an exam with 400 possible points and are told that the mean score is 280 and that the standard deviation is 20. You are also told that you got 350. The test scores are normally distributed. Did you do well on the exam? Explain your answer. (Hint: calculate the z score to see how many standard deviation your score is away (above or below) from the mean and then discuss)
