A laboratory in New Mexico 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 chloride level of 104mEq/L. If it is known that the chloride levels in healthy individuals residing in New Mexico have a standard deviation of 38mEq/L, find a 95% confidence interval for the true mean chloride level of all healthy New Mexico residents. Then complete the table below.

Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.

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

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