A laboratory in Alaska is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 80

healthy residents has a mean chloride level of 100

mEq/L. If it is known that the chloride levels in healthy individuals residing in Alaska have a standard deviation of 37

mEq/L, find a 95

%

confidence interval for the true mean chloride level of all healthy Alaska residents. 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 95

%

confidence interval?

What is the upper limit of the 95

%

confidence interval?
