19 = 10 = 11 = 12 13 = 14 15 16 17 18 19 A laboratory in Alaska is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 90 healthy mEq residents has a mean chloride level of 100 L . If it is known that the chloride levels in healthy individuals residing in Alaska have a mEq standard deviation of 36 L , find a 90% confidence interval for the true mean chloride level of all healthy Alaska residents. Then give its lower limit and upper limit. 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: I1 X Upper limit
