A laboratory in Colorado is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 60 healthy residents has a mean chloride level of

105 mEq/L.If it is known that the chloride levels in healthy individuals residing in Colorado have a standard deviation of 36 mEq/L,find a 99% confidence interval for the true mean chloride level of all healthy Colorado 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 alist of formulas.)

Lower limit:
Upper limit:
