A researcher collected sample data for17women ages18to24. The sample had a mean serum cholesterol level (measured in mg/100 mL) of192.2, with a standard deviation of8.2. Assuming that serum cholesterol levels for women ages18to24are normally distributed, find a90% confidence interval for the mean serum cholesterol level of all women in this age group. Then complete the table below.
Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
What is the lower limit of the confidence interval?
What is the upper limit of the confidence interval?
