1. Review the definition of percentile.

2. Review how you have been taught to do inverse normal calculations, that is, how to fnd the value of x such that Pr(X < x) = a given probbaility. (You will also find many examples in this subforum).

Once you have done this, please show what progress you have made in answering the question and say where you get stuck.
