A random sample of 100 healthy residents has a mean chloride level of 102 mEq/L. If it is known that the chloride levels in healthy individuals have a standard deviation of 40 mEq/L, find a 95% confidence interval for the true mean chloride level of all healthy residents. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
What is the lower limit of the 95% confidence interval?
What is the upper limit of the 95% confidence interval?
