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 0.84 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 3.19 milligrams. (b) The sample mean is 30 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. Click here to view page 1 of the Standard Normal Table. Click here view page 2 of the Standard Nomal Table. (a) The minimum sample size required to construct a 95% confidence interval is 56 servings. (Round up to the nearest whole number.) (b) The 95% confidence interval is (O.). It V seem likely that the population mean could be within 3% of the sample mean because 3% off from the sample mean would fall V the confidence interval, It se- that the population mean could be within 0.3% of the sample mean because 0.3% off from the sample mean would fall V the confidence interval. (Round to two decimal places as needed.)

Transcribed Image Text: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 0.84 milligram of the population mean.
(a) Determine the minimum sample size required to construct a 95% confidence interval for the population mean. Assurne the population standard deviation is 3.19 milligrams.
(b) The sample mean is 30 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.
