Question 1131236: Find the minimum sample size you should use to assure that your estimate if p will be within the required margin of error around the population p. Margin of error: 0.05; confidence level: 99%; from a prior study, p is estimated by 0.13 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! margin of error is sqrt(p*(1-p)/n)*2.576, the z-value for 99%
=sqrt(0.13*0.87/n)*2.576=0.05
square both sides
0.0025=6.64*.13*.87/n
n=300.39 or 301
