A large study of the heights of 1010 adult men found that the mean height was 70 inches tall. The standard deviation was 6 inches. If the distribution of data was normal, what is the probability that a randomly selected male from the study was between 64 and 82 inches tall? Use the 68-95-99.7 rule (sometimes called the Empirical rule or the Standard Deviation rule). For example, enter 0.68, NOT 68 or 68%.
Round your answer to three decimal places.
Caution: Using tables or Excel for this may produce a wrong answer. Use the 68-95-99.7 rule.
