A machine at a soft-drink bottling factory iscalibrated to dispense 12 ounces of cola intocans. A simple random sample of 35 cans ispulled from the line after being filled and thecontents are measured.The mean content of the 35 cans is 11.92 ounceswith a standard deviation of 0.085 ounces.Estimate the true mean contents of the cansbeing filled by this machine with 95%confidence.
