A laboratory in California is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 50 healthy residents has a mean chloride level of 101 mEqL. If it is known that the chloride levels in healthy individuals residing in California have a standard deviation of 35 mEqL, find a 95% confidence interval for the true mean chloride level of all healthy California 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: Upper limit:
