Question

If a school had 1531 students, about how many would you expect to have an IQ greater than 145?

Answer 1

383 students

Explanation:

Average IQ = 115

So for IQ of 145 it's not average again.

So , 145 IQ should be 1/4 of the total number because it's no longer average .

So 1/4 of 1531 = 382.75 students approximately = 383 students

This answer is based on the assumption that average IQ is around 115.

So any one with IQ of 145 is not longer an average person concerning IQ.
