I went to

http://davidmlane.com/hyperstat/z_table.html

and entered the values to get

.8694

This is a routine question. I don't know if you use tables in the back of your book or use a webpage like I linked to.

If you are studying this topic, your statement of

"I don't understand how to do this", puzzles me.
