A large group of students take an examination (top score, 100), and the results are normally distributed. The mean score on the examination is 82, with a standard deviation of 6.58. A study group of four students obtain scores of 78, 82, 88, and 95. For each score, compute the corresponding z-score and find its percentile rank. Round the z-scores to the nearest hundredth place.
