A researcher collected sample data for 16 women ages 18 to 24 . Thesample had a mean serum cholesterol level (measured in mg/100 mL) of 188.7 , with astandard deviation of 7.2 . Assuming that serum cholesterol levels for women ages 18 to 24 arenormally distributed, find a 95%confidence interval for the mean serum cholesterollevel 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?
