A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1537 and the standard deviation was 317. The test scores of four students selected at random are 1950, 1250, 2240, and 1420. Find the z-scores that correspond toeach value and determine whether any of the values are unusual.The Z-score for 1950 is.(Round to two decimal places as needed.)C
