    Hello student,

    Since on this problem

    mean= 0
    standard deviation= 1

    We know the intention is for us to consult standard tables. Your textbook should have a "Standard Normal Table" although the name may slightly vary and the values may have three or four decimal places. Use your book's table for your homework.

    In this example I will use the one from Wikipedia: ...

    Solution Summary

    This solution explains how to calculate unit normal probabilities in the form of p (-1.96 < z < 2.60) from a table and checking with a calculator using values of mean=0 and standard deviation=1.
