Hi all, I'm a bit rusty on the stats and can't work out how to do this problem:

Have a batch of 100, need a sample n such that i get a confidence c that this sample is representative of the batch.
 

Excel Facts

Using Function Arguments with nested formulas
If writing INDEX in Func. Arguments, type MATCH(. Use the mouse to click inside MATCH in the formula bar. Dialog switches to MATCH.

Try this

=CONFIDENCE(D6,3,100)

selecting =confidience gives some options and ranges to choose.


Hope this helps
