Question

Assume that adults have IQ scores that are normally distributed with a mean of 97 and a standard deviation 24. Find the first

Answer 1

Answer #1

The formula for the first quartile in the normal distribution is Mean - (0.675)*(Standard deviation)

Here, mean = 97

Standard deviation = 24

Hence the first quartile will be 97-(24)*(0.675) = 80.8

Hence the required answer is 80.8
