A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1467 and the standard← deviation was 320. The test scores of four students selected at random are 1850, 1210, 2210, and 1360. Find thez-scores that correspond to each value and determine whether any of the values are unusual.The Z-score for 1850 is(Round to two decimal places as needed.)The Z-score for 1210 is(Round to two decimal places as needed.)The Z-score for 2210 is(Round to two decimal places as needed.)The Z-score for 1360 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 yourchoice.OA. The unusual value(s) is/are(Use a comma to separate answers as needed.)OB.

Note: The standard deviation is defined as the average distance of the class scores from the mean. Note: The variance is defined as average squared distance of the class scores from the mean.

Listed in the data table are IQ scores for a random sample of subjects with medium lead levels in their blood. Also listed are statistics from a study done of IQ scores for a random sample of subjects with high lead levels.
