Question: 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 did not bother them , such as a beach or a 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 α = .05.
