Please make sure it's the correct answer

A researcher collected sample data for 9 women ages 18 to 24. The sample had a mean serum cholesterol level (measured in mg/100 mL) of 190.2, with a standard deviation of 8.5. Assuming that serum cholesterol levels for women ages 18 to 24 are normally distributed, find a 95% confidence interval for the mean serum cholesterol level of all women in this age group. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit: X ? Upper limit
