how to find sample size with confidence interval and standard deviation

Sagot :

In order to estimate the sample size, we need approximate values of p1 and p2. The values of p1 and p2 that maximize the sample size are p1=p2=0.5. Thus, if there is no information available to approximate p1 and p2, then 0.5 can be used to generate the most conservative, or largest, sample sizes.
