IQ data is thought to be normally distributed with a mean of 100 and a standard deviation of 15. Using the emperical rule, what is the IQ range we would expect approximately 95% of the population to be? Make a sketch of the IQ distribution and using the normal z chart, find the probability of having an IQ greater than 132. This is the minimum Standford-Binet IQ score required to join Mensa, The largest IQ society in the world.
