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

Which came first: VisiCalc or Lotus 1-2-3?
Dan Bricklin and Bob Frankston debuted VisiCalc in 1979 as a Visible Calculator. Lotus 1-2-3 debuted in the early 1980's, from Mitch Kapor.

Try this

=CONFIDENCE(D6,3,100)

selecting =confidience gives some options and ranges to choose.


Hope this helps
