i would like to able to find the percentile rank of a z score 0.313152
can someone tell me how to do this.
It's about 62.3%. That is the fraction with LOWER z-scores.
I used an online normal distribution calculator.

There are many others you can find with Google.
round it if its about 62.3% then its closest to 62 percent
