What is the advantage of a larger sample size?
There is a higher probability
σp
will be within ±0.04 of the population standard deviation.We can guarantee
p
will be within ±0.04 of the population proportion p. As sample size increases,
E(p)
approaches p.There is a higher probability
p
will be within ±0.04 of the population proportion p.
