ABC university claims that because of its superior facilities and close faculty supervision, its students complete the Ph.D program earlier than usual. They base this assertion on the fact that the population mean age for the for completion is u=32.11. Their n=31 Ph.D's have a mean age of M=30.89, with a standard deviation of s=4. Test the validity of this assertion using a two-tailed year with alpha set to =.05.
