Hugo averages 76 words per minute on a typing test with a standard deviation of 12.5 words per minute. Suppose Hugo's words per minute on a typing test are normally distributed. Let X= the number of words per minute on a typing test. Then, X∼N(76,12.5). Suppose Hugo types 66 words per minute in a typing test on Wednesday. The z-score when x=66 is . This z-score tells you that x=66 is standard deviations to the (right/left) of the mean, .
