A researcher collected sample data for 16 women ages 18 to 24 . The sample had a __mean__ serum cholesterol level (measured in mg/100 mL) of 190.4, with a __standard deviation__ of 7.4 . Assuming that serum cholesterol levels for women ages 18 to 24 are __normally distributed__, find a 90% __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.

(If necessary, consult a __list of formulas__.)

What is the lower limit of the confidence interval?

What is the upper limit of the confidence interval?
