Math Is Fun Forum

I am at college level "Math For Liberal Arts".. we are in our last chapter and it's Statistics:

Find the z-score that best satisfies the condition.

14% of the total area is to the left of z.

I thought I understood the basics of this, but I'm frustrated and really confused. Anytime I have to find a number from the "Areas Under the Standard Normal Curve" chart I get the wrong number. I don't know what I'm doing wrong.. can someone please help me?
