Suppose you would like to conduct a survey to determine the yearly consumption of beef by a typical American and want to use 3 pounds as the desired margin of error estimate of the population mean amount of beef consumed annually. Use 25 pounds as the population standard deviation and recommend a sample size for each of the following situations: a. A 90% confidence interval is desired. b. A 95 % confidence interval is desired. c. A 99% confidence interval is desired.
