Example 25


Example 25: The average weight of 19 year old males is 176.8 pounds.  The standard deviation is 26.4 pounds.  If there is reason to believe that the distribution of weights for 19 year old males is normally distributed (or bell shaped), what is the approximate percentage of 19 year old males that will weigh between 150.4 pounds and 203.2 pounds?
