        About Hypothesis Tests II
            Corrections for "About Hypothesis Tests II":
            (1)for                                    on the first page, this should say: Power = (1 - β); where β = P(Type II Error)
                                              
                                (2) for                                                                             on the second page, the t* should be a z*
