We will use a z-score to answer this question. z-scores are given by the formula

With our information, we have

Looking this up in a z-table (http://www.z-table.com) we see that the area to the left of this (everything less than, up to this value) is 0.8997.
3+p=8
-p -p
3=8-p
-8 -8
-5=-p
swap signs
5=p
Answer:
