A research team wants to investigate the usefulness of relaxation training for reducing levels of anxiety in individuals experiencing stress. They identify 30 people at random from a group of 100 who have "high stress" jobs. The 30 people are divided into two groups. One group acts as the control group they receive no training. The second group of 15 receive the relaxation training. The subjects in each group are then given an anxiety inventory. The summarized results appear below where higher scores indicate greater anxiety. The raw data appear below. Evaluate her experiment using the criteria of p < 0.05. Assume it is a two tailed test. YSou need to perform the 5 steps in Hypothesis Testing.
