A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1521 and the standard deviation was 320. The test scores of four students selected at random 1910, 1280, 2250, and 1420. 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.) The z-score for 1280 is. (Round to two decimal places as needed.) The z-score for 2250 is (Round to two decimal places as needed.) The z-score for 1420 is (Round to two decimal places as needed.) Which values, if any, are unusual? Select the correct choice below and, if necessary, fill in the answer box within your choice. OA. The unusual value(s) is/are (Use a comma to separate answers as needed.) OB. None of the values are unusual.
