Step-by-step explanation:

What is the z-score of a value of 27, given a set mean of 24, and a standard deviation of 2? To find the z-score we need to divide the difference between the value, 27, and the mean, 24, by the standard deviation of the set, 2. This indicates that 27 is 1.5 standard deviations above the mean.
