A soft drink company produces a cola in a 12-ounce can. Even though their machines are set to fill the cans with 12 ounces, variation due to calibration, operator error, and other things sometimes precludes the cans having the correct fill. To monitor the can fills, a quality team randomly selects some filled 12-ounce cola cans and measures their fills in the lab. A confidence interval for the population mean is constructed from the data.

Shown here is the Minitab output from this effort. Discuss theoutput.
