Question
![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)
(d) Conclusion of the test above is
Reject the null hypothesis and the mean daily yield for the new process is less
than that of the old procedure.
Do not reject the null hypothesis and the mean daily yield for the new process is
not less than that of the old procedure.
Reject the null hypothesis and the mean daily yield for the new process is not
less than that of the old procedure
