A standardized exam's scores are normally distributed. In a recent year, the mean test score was 20.6 and the standard deviation was 5.6. The test scores of four students selected at random are 13, 23, 7, and 35. Find the z-scores that correspond to each value and determine whether any of the values are unusual. Question content area bottom Part 1 The z-score for 13 is (Round to two decimal places as needed.) Part 2 The z-score for 23 is (Round to two decimal places as needed.)
