Suppose we want to estimate the proportion of men smokers in a firm having 1500 total employees. Assume 30 out of 100 employees are men, and the sample is drawn by simple random sampling without replacement. Find the sample size to be selected so that the total length of confidence interval with confidence level 0.05 is less than 0.02. (z = 1.96). 1.
