A marketing researcher is hired by a corporation to conduct a study and estimate the population mean for the attribute of interest using a 90% confidence interval with a maximum error of 2.5. It will cost the researcher $5 per sample to conduct the study and the researcher has been given a budget of $1,200 to conduct the study. Based on prior studies the researcher can estimate the standard deviation using, σ≈15�≈15.   Step 2 of 3 :   How much will it cost the researcher to conduct this study?
