4) Question: A sample of 40 patients shows that their average cholesterol level is 200 mg/dL with a standard deviation of 20 mg/dI.. Construct a 99% confidence interval for the population mean cholesterol level.
We have developed a new drug used to reduce fever and want to test its efficacy. Ten ER patients who are running a fever agree to take the new drug instead of the traditional treatment. Their temperatures are taken before the drug is administered and 30 minutes after taking the drug. The results are recorded in the Excel file below. Use the data to construct and interpret a 99% confidence interval for the mean change in temperatures of patients after taking this drug using Excel. Be sure to include any explanation necessary along with a sentence that explains what the interval means.

A manufacturer wants to estimate the standard deviation of the lifetime of the AAA batteries it produces. A random sample of 21 AAA batteries produced by this manufacturer lasted a mean of 10.4 hours with a standard deviation of 2.3 hours. Find a 90% Confidence interval for the population standard deviation of the lifetimes of AAA batteries produced by the manufacturer. Then give its lower limit and upper limit.
