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. Use z-table. a. n = 100 0.5878 b. n = 200 0.7499 c. n = 500 0.9328 d. n = 1000 0.9901 e. What is the advantage of a larger sample size? With a larger sample, there is a higher probability will be within ±0.04 of the population proportion p.
