Hi 
 95% confident ⇒  z = 1.96, 
p = .50(Generally .5 is used if p is not given)  ME = .03
How large of a sample size is required?
n = {{{(z/ME)^2 (p(1-p)))}}}
n = {{{(1.96/.03)^2 (.5(.5)))}}} = 1067.11  0r sample Size = 1068

 = CI	z = value
90%	z =1.645
92%	z = 1.751
95%	z = 1.96
98%	z = 2.326
99%	z = 2.576
Wish You the Best in your Studies.
