49. Cholesterol Contents of Cheese 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 0.75 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 3.10 milligrams. (b) The sample mean is 29 milligrams. Using the minimum sample size with a 95% level of confidence, does it seem possible that the population mean could be within 3% of the sample mean? within 0.3% of the sample mean? Explain.

Question

A cheese processing company wants to estimate the mean cholesterol of all one ounce serving of a type chesse. The estimate must be within .75 milligram of the population mean.

B) the sample mean is 29 milligram. Using the minimum sample size(66) with a 95% confidence does it seam possible that the population mean could be withing 3%? Within .3% of the sample mean? Explain

49. Cholesterol Contents of Cheese 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 0.75 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 3.10 milligrams.
(b) The sample mean is 29 milligrams. Using the minimum sample size with
a 95% level of confidence, does it seem possible that the population
mean could be within 3% of the sample mean? within 0.3% of the
sample mean? Explain.
