In the past, a chemical company produced 880 pounds of a certain type of astic per day. Now, using a newly developed and less expensive process, the mean aily yield of plastic for the first 50 days of production is 871 pounds; the standard leviation is 21 pounds. Do the data provide sufficient evidence to indicate that the mean daily yield for the new process is less than that of the old procedure? (Use α=0.05) (a) Alternative hypothesis for the problem above is
