A study to be conducted of the percentage of homeowners who have a high speed internet connection. How large a sample is required if we wish to be 95% confident that the error in estimating this quantity is less than 0.02?

Compute Sample Size ( n ) = n=(Z/E)^2*p*(1-p)
Z a/2 at 0.05 is = 1.96
Samle Proportion = 0.5
ME = 0.02
n = ( 1.96 / 0.02 )^2 * 0.5*0.5
= 2401 ~ 2401
