Essay questions:
2. A marketing research manager intends to survey a simple random sample of Swiss consumers and ask questions about level of beverage consumption. How can she estimate the population standard deviation for this variable before selecting the sample? Why would she need to do that? What would happen if her initial estimate were not reflected in the sample results (i.e., if the estimated standard deviation in the sample turned out to be larger than expected)?
