Suppose a survey researcher, studying expenditures on lipstick, wishes to have a 99 percent confident level and a range of error of less than $2.00. The estimate of the standard deviation is $29.00. What is the final sample size required? If only 50 percent of households contain women who use lipstick and on average only 20 percent of people contacted actually complete the survey, what is the initial numbers of households that need to be contacted?
