Answer both questions 

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 0.71 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 3.05 milligrams.
(b) The sample mean is 25 milligrams. Using the minimum sample size with a 95% level of confidence, does it seem likely that the
population mean could be within 3% of the sample mean? within 0.3% of the sample mean? Explain.
