It has been found that IQ scores are normally distributes with a mean of 108 and a standard deviation of 16 points. 
A person must score in the upper 2% of the population in an IQ test to qualify for membership in Mensa. What is the minimum score that one has to achieve in order to qualify for Mensa?

Find the z-score with a right-tail of 0.02.
invNorm(0.98) = 2.0537

Find the corresponding IQ score:
x = zs + u
x = 2.0537*16 + 108
x = 140.86
