Extracted text: 1 4. 10 A laboratory in New York is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 80 healthy residents has a mean mEq chloride level of 103 If it is known that the chloride levels in healthy individuals residing in New York have a standard deviation of 39 L mEq find a 95% confidence interval for the true mean chloride level of all healthy New York 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: I Upper limit:
