How to calculate sampling error and confidence level from the data table on gender:

.60 x .40/15 = .24/15=.016 and then hit the square root key which gives you .1264911 X 2 = .2529 rounded off to .25 or 25%. This becomes your sampling error and then substract that from 100% = 75% confidence level.

You use this formula to figure out the sampling error and confidence level for your own project.
