The article "Should Canada Allow Direct-to-Consumer Advertising of Prescription Drugs?"† calls for the legalization of advertising of prescription drugs in Canada. Suppose you wanted to conduct a survey to estimate the proportion of Canadians who would allow this type of advertising. How large of a random sample would be required to estimate this proportion with a margin of error of 0.02? (Round your answer up to the nearest integer.) Assume a 95% confidence level and the population proportion, p = 0.50.
Homework Answers
Preliminary estimate for proportion (Known) = 0.5
Margin of error =E=0.02
Level of significance =1-0.95=0.05
Z critical value is (by using Z table) =1.96
Sample size formula is
=2400.91
Therefore, sample size approximately will be 2401
