Use 25 pounds as a planning value for the population standard deviation and recommend a sample size for each of the following situations. a. A 90% confidence interval is desired for the mean amount of beef consumed. b. A 95% confidence interval is desired for the mean amount of beef consumed. c. A 99% confidence interval is desired for the mean amount of beef consumed.
