If it is known that the chloride levels in healthy individuals residing in Florida have a standard deviation of 38mEqL, find a 90% confidence interval for the true mean chloride level of all healthy Florida 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.
