A business researcher has to decide which of three employees should be placed in a particular job that requires a high level of perceptual-motor coordination. All three employees have taken tests of perceptual-motor coordination, but each took a different test. Employee A scored 15 on a test with a mean of 10 and a standard deviation of 2. Employee B scored 350 on a test with a mean of 300 and a standard deviation of 40. Employee C scored 108 on a test with a mean of 100 and a standard deviation of 16. On all three tests, higher scores mean greater coordination.
Which employee has the best perceptual-motor coordination? Be sure to explain the calculations you used in determining the answer?
