A yoga instructor gets a sample of 75 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. For those doing 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 6. At the alpha = 0.01 level, is her hypothesis supported?
