- Gail averages 64 words per minute on a typing test with a standard deviation of 9.5 words per minute. Suppose Gail'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(64,9.5). If necessary, round to three decimal places. Provide your answer below: Suppose Gail types 89 words per minute in a typing test on Sunday. The z-score when x = 89 is . The mean is .
