The New You Cancer Center (Not a Real Entity) Promotes

question 10

Multiple Choice

The New You Cancer Center (not a real entity) promotes therapies outside ordinary, Western medicine: meditation, crystals, yoga-and 197 others. To investigate the efficacy of these therapies, a researcher hired by the center conducted a study with 150 adult subjects who were patients at the center. At the end of the study, the effect of the 200 therapies on the subjects were measured. Nine of these therapies were found to have made the subjects' "quality of life metric" significantly better (in the sense of statistical significance) at the  = 0.05 level compared to a control group, and one therapy was significantly better at the  = 0.01 level compared to a control group. It would be correct to conclude:

• A) there is very good statistical evidence that these (significant) therapies provide some improvement in cancer patients' quality of life.
• B) there is very good statistical evidence that the therapy that was significant at the 0.01 level provides improvement for cancer patients' quality of life. We should be somewhat cautious about making claims for the therapies which were significant at the  = 0.05 level.
• C) these results would have provided very good statistical evidence that the therapies provide some improvement in cancer patients' quality of life if the number of subjects had been larger. It is premature to draw statistical conclusions from studies in which the number of subjects is less than the number of variables measured.
• D) none of the answer choices are correct.
