The problem goes as such;
The scale of scores on an IQ test is approximately Normal with mean 100 and standard deviation 15. The organization MENSA, which calls itself "the high-IQ society," requires an IQ score of 130 or higher for membership. What percent of adults would qualify for membership?
I know I can use the 68-95-99.7 rule, but I am confused at where to begin.
