A standardized exam is known to be normally distributed with a mean score of 82 and a standard deviation of 6.58 in the examination. (Hint: so this means you can convert individual exam scores to z-scores and calculate percentile rank). One student named Amy has an exam score of 78. For Amy's score, compute the corresponding z score. Make sure to round the z-score to the nearest hundredth place (Hint if the z-score is 0.3615, then you round it to 0.36).
