A laboratory in Colorado is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 70 healthy residents has a mean mEq chloride level of 99 If it is known that the chloride levels in healthy individuals residing in Colorado have a standard deviation of 36 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 a list of formulas.) mEq find a 95% . L Lower limit: Upper limit: X Ś
