A researcher is conducting an experiment to evaluate the effectiveness of cognitive-behavioral therapy in treating eating disorders. The mean eating disorder score in clinical population of people suffering from the disorder is μ = 75. The results of the experiment will be examined by a z -test, two-tails. Which of the following is the correct statement of the alternative hypothesis, H1? A. μ = 75 (i.e., the treatment has a significant effect). B. μ ≠ 75 (i.e., the treatment has no significant effect). C. μ ≠ 75 (i.e., the treatment has a significant effect). D. μ = 75 (i.e., the treatment has no significant effect).
