Question
A cheese processing company wants to estimate the mean cholesterol content of all one-ounce servings of a type of cheese. The estimate must be within 0.79 milligram of the population mean. (a) Determine the minimum sample size required to construct a 95% confidence interval for the population mean. Assume the population standard deviation is 3.16 milligrams. (b) The sample mean is 26 milligrams. Using the minimum sample size with a 95% level of confidence, does it seem likely that the population mean could be within 4% of the sample mean? within 0.4% of the sample mean? Explain. Click here to view page 1 of the Standard Normal Table. Click here view page 2 of the Standard Normal Table. (a) The minimum sample size required to construct a 95% confidence interval is (Round up to the nearest whole number.) servings.
