A) state null and alternative hypotheses B) give test statistic and p value

Mind-Set Matters In 2007 a Harvard psychologist set out to test her theory that "Mind-Set Matters." She recruited 75 female maids working in different hotels to participate in her study, and informed 41 maids (randomly chosen) that the work they do satisfies the Surgeon General's recommendations for an active lifestyle (which is true), giving the maids examples on how their work qualifies as good exercise. The other 34 maids were told nothing. After four weeks, the exercise habits of the two groups had not changed, but the informed group had lost an average of 1.79 Ibs (s = 2.88) and the uninformed group had lost an average of 0.2 Ibs (s = 2.32). The data are stored in MindsetMatters. Based on this study, does "Mind-Set Matter"? In other words, for maids, does simply thinking they are exercising more actually cause them to lose more weight?
