We have specified a margin of error, a confidence level, and a likely range for the observed value of the sample proportion. For each exercise, obtain a sample size that will ensure a margin of error of at most the one specified (provided of course that the observed value of the sample proportion is further from 0.5 then the educated guess).

margin of error = 0.01; confidence level = 95%; likely range = 0.2 to 0.4
