A laboratory in California is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 150 healthy residents has a mean chloride level of 105 mEq/L. If it is known that the chloride levels in healthy individuals residing in California have a standard deviation of 39 mEq/L, find a 95% confidence interval for the true mean chloride level healthy California residents.
What is the lower limit of the 95% confidence interval?
What is the upper limit of the 95% confidence interval?
