Helping with getting the sample size?
I would appreciate any help I can get with this question.
Suppose we wish to select a simple random sample without replacement from a population of size 1000 to estimate the proportion, P, of population members with a particular characteristic, and we want the relative standard error (RSE) to be about 8%. From a previous survey we have a reliable estimate, 0.32, of this proportion.
Find the minimum sample size required to meet this sample design constraint.
but solving for n, I got a number less than 1! What have I done wrong?!?! Please help :)
(and sorry I didn't use Latex, I got an error :( )
