We did a phone survey at work for a client. He's asked me to do up a report on the results. He wants a blurb like "A sufficient return on the sample was received to provide for a statistical level of validity 19 times out of 20 +/- 1.98%."

It has been a loooong time since I took this stuff in University. I'm wondering if someone can help me figure out the +/- thing for the survey we did.

We completed 396 surveys out of about 1600 households.

Thanks in advance.
