Retest

The Members of the newest recruiting class of an organization are taking their physical test and those who score in the bottom 16 % will have to retest. If the scores are distributed normally and have an arithmetic mean of 72, what is the score at or below which the recruits will have to retest?

1.) there are 500 recruits in the class.
2.) 10 recruits scored 82 or higher.
