2. Researchers have sought to examine the effect of various types of music on agitation levels in patients who are in the early and middle stages of Alzheimer's disease. Patients were selected to participate in the study based on their stage of Alzheimer's disease. Three forms of music were tested: Easy listening, Mozart, and piano interludes. While listening to music, agitation levels were recorded for the patients with a high score indicating a higher level of agitation. Scores are recorded below. Perform a two-way ANOVA and interpret the results. Test at the 0.05 level. Use Excel and attach the printout. Group mean=21.0 Piano Interlude mean:a.0 Mozart mean= 27.0 Easy Listening 21 9. 29 24 12 26 Early Stage Alzheimer's 22 10 30 18 5 24 20 9. 26 22 14 15 20 18 18 Middle Stage Alzheimer's 25 11 20 18 9. 13 20 19 13 mean-13.0 mean = 21.0 mean =17.0
