A laboratory in Colorado is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 150 healthy residents has a mean chloride level of 106 mEq/L. If it is known that the chloride levels in healthy individuals residing in Colorado have a standard deviation of 45 mEq/L, find a 99% confidence interval for the true mean chloride level of all healthy Colorado residents. Then complete the table below. What is the lower limit of the 99%
confidence interval?
What is the upper limit of the 99%
confidence interval?

Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
