A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1477 and the standard deviation was 319. The test scores of four students selected at random are 1870, 1230. 2230. and 1330. Find Ihe 2-5me that correspond to each value and determine wheiher any of the values are unusual. The zsmre for 1870 is . (Round In two decimal places as needed.) The zsoore for 1230 is . {Round in two decimal places as needed.) The zscore lor 2230 is . {Round in two decimal places as needed.)
