Now, using a newly developed and less expensive process, the meandaily yield of plastic for the first 50 days of production is 871 pounds; the standarddeviation is 21 pounds.Do the data provide sufficient evidence to indicate that the mean daily yield for thenew process is less than that of the old procedure?
