    What is 64.7%? It's a probability of 64.7/100 = 0.647.

    Now, sketch the z distribution curve, and estimate the location of the z value. Obviously it's a negative number.

    Now, to what z value does the probability of 0.647 belong to in your z table?

    Depending on what type of z table you're using, you'll have a certain value of z. Do the necessary changes if needed to get the z value you're looking for.

    Since 64.7% lies to the right, then 1-.647=.353 must lie to the left.
    Look up .353 in the z-table and find its corresponding z value.
