You are working with a MOE of +/-4% and a confidence level of 95%. P and Q =.50, and your CPI is $25.00. The company you work for needs to make a decision as to whether they may need different advertising for men and women. So, your supervisor wants to know if men and women differ in their response to the company's advertising. You are in charge of designing and running this research study.
Given the parameters, what will be your sample size for this study. Now, if you want to assume a MOE of at least +/-4% for men and for women, how many men and women will you want to interview? What will this particular study cost? Now, suppose you have a budget of $60,000. Is it enough for the budget? Please explain answers.
