A researcher knows that the mean number of symptoms (e.g., fatigue, sleep disturbance, feelings of worthlessness, etc.) exhibited by the population of people with unipolar depression, prior to diagnosis, is 9.5. They suspect that being told that you suffer from unipolar depression increases that number. They randomly select 14 individuals already with the diagnosis of unipolar depression and counts the number of symptoms they exhibit. The number of depressive symptoms exhibited by the 14 participants was: 8, 9, 15, 19, 12, 8, 16, 14, 12, 13, 16, 5, 19, 10 Does the researcher’s hypothesis carry any weight at the .05 level? Complete a 6-step hypothesis test with alpha = .05. What do you conclude? please show using excel also. Thanks
