Six hundred of the best students are to be picked from 5,000 students in order for them to go on a special education programme. Assume that IQ is an appropriate way to pick the 600 students. We wish to know the minimum IQ score such that there are 600 students with that IQ or higher. What is this IQ score given that the mean IQ of the population is 90 with a standard deviation of 15? Show how you arrived at your answer.
Hint- tyou'll be expected to assume it's a normal distribution.
Now have ago -it's the best way to learn. Giving you the answer is a short cut that doesn't help much in the long run.
Good luck
