f Suppose that you take an exam with 391 possible points and are told that that mean score is 270 and that the standard deviation is 22. You are also told that you got 346. Did you do well on the exam? Explain your answer. Determine the z-score and interpret this score. A score of 346 has a z-score of. This is standard deviations the mean for this exam. The this score is the mean, this is a score. (Round to two decimal places as needed.) standard deviations states that approximately 99.7% of the observations lie within standard deviations of the mean. Sine
