A marketing researcher is hired by a corporation to conduct a study and estimate the population mean for the attribute of interest using a 98% confidence interval with a maximum error of 5. It will cost the researcher $15 per sample to conduct the study and the researcher has been given a budget of $750 to conduct the study. Based on prior studies the researcher can estimate the standard deviation using, σ≈16�≈16. Step 2 of 3: How much will it cost the researcher to conduct this study?
