This is my first time to this forum.....I wish I had found it earlier in my Stats class.

My question is:

Where would I go to find the z-score that corresponds to different percentile?

For example the 35th or the 72nd or what not.

I know that the mean is o and 1 standard deviation to either side is about 34%.

Please help!!!

The z-score that corresponds to the 72nd percentile?
