A laboratory in Arizona is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 100 healthy residents has a mean chloride level of 103 mEqL. If it is known that the chloride levels in healthy individuals residing in Arizona have a standard deviation of 45 mEqL, find a 90% confidence interval for the true mean chloride level of all healthy Arizona 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 Lower limit: Upper limit:
