Weekly the 30,000-foot-level sample measurements from a new process were 22, 23, 19, 17, 29, and 25. Create an appropriate time-series reporting system for this process. Determine the confidence interval for the mean and variance. If a computer program is used for the computation, also show the appropriate equations. Comment on the results.
