The weights of members of a baseball league are normally distributed with a mean of 176 pounds and a standard deviation of 11.4 pounds. Consider a league membership of 120 members.

How many of the members will weigh 165 pounds or more?

176 - 165 = 11 pounds 11/11.4 standard deviations below the mean = .9649 S.D. below the mean (z-score)

z-score: -.96 = .1685 or ~ 17% are below 165 so the rest are above or 83 %
