1. In the past, a chemical company produced 880 pounds of a certain type of
plastic per day. Now, using a newly developed and less expensive process, the mean
daily yield of plastic for the first 50 days of production is 871 pounds; the standard
deviation 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 a=0.05)
