A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1466 and the standard deviation was 316. The test scores of four students selected at random are 1910, 1200, 2150, and 1370. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The Z-score for 1910 is (Round to two decimal places as needed.)
