If it is known that the chloride levels in healthy individuals residing in Washington have a standard deviation of 44mEq/L, find a 95% confidence interval for the true mean chloride level of all healthy Washington residents. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. 

What is the lower limit of the 95% confidence interval?

What is the upper limit of the 95% confidence interval?
