The population proportion is 0.40. What is the probability that a sample proportion will be within ±0.04 of the population proportion for each of the following sample sizes? (Round your answers to 4 decimal places.)
(a) n = 100
(b) n = 200
(c) n = 500
(d) n = 1,000
(e) What is the advantage of a larger sample size?
We can guarantee p will be within ±0.04 of the population proportion p.
There is a higher probability σp will be within ±0.04 of the population standard deviation.
As sample size increases, E(p) approaches p.
There is a higher probability p will be within ±0.04 of the population proportion p.
