Langewitz, Izakovic, and Wyler (2005) reported that self-hypnosis can significantly reduce hay fever symptoms. Patients with moderate to severe allergic reactions were trained to focus their minds on specific locations where their allergies do not bother them, such as a beach or ski resort. In a sample of 64 patients who received this training, suppose that 47 showed reduced allergic reactions and 17 showed an increase in allergic reactions. Are these results sufficient to conclude that the self-hypnosis has a significant effect? Assume that increasing and decreasing allergic reactions are equally likely if the training has no effect. Use a = .05..
