Assume that adults have IQ scores that are normally distributed with a mean of 100 and a standard deviation 15. Find Upper P 2P2, which is the IQ score separating the bottom 22% from the top 98%.
Answer
Using invNorm
setting
area = 0.22 (bottom 22%)
mean = 100
standard deviation = 15
we get
P22 = invNorm(area, mean,sd)
= invNorm(0.22,100,15)
= 88.42
