Answer:
383 students
Step-by-step 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.
