Question 905950: Find the minimum sample size that should be chosen to assure that the proportion estimate p will be within the required margin of error, .06. Use a 95% confidence interval and a population proportion of .7. The critical value for a 95% confidence level is 1.96 Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website!
You may use Your TI (or any other calculator for the Arithmetic...)
this one is a need to know: ME = 0r ME = when You do not know
ME = .07 = 1.96sqrt(.7*.3/n)
(.07/1.96)^2 = .21/n
n = .21/(.07/1.96)^2 = 164.64 0r 165 (always round Up for number of people)
