A yoga instructor believes that regular practice of yoga exercises can reduce anxiety better than meditation can. She gets a sample of 74 people and randomly assigns half of them to do the yoga 3 times per week and half to engage in meditation 3 times per week. After 6 weeks, she measures all participants on the State Anxiety Scale (higher scores = more anxiety). For those doing the yoga, the mean anxiety score is 9.5 with a standard deviation of 3, for those doing the meditation, the mean anxiety score is 11.7 with a standard deviation of 4. At the =.01 level, is her hypothesis supported?
