Imagine a researcher wants to determine whether or not a given drug has any effect on the scores of human subjects performing a task of ESP (Extrasensory perception) sensitivity. He randomly assigns his subjects to one of two groups. Nine hundred subjects in group 1 (the experimental group) receive an oral administration of the drug prior to testing. In contrast, 1000 subjects in group 2 (control group) receive a placebo. For the drug group, the mean score on the ESP test was 9.78, S.D. = 4.05, n = 900 or the placebo group, the mean = 15.10, S.D. = 4.28, n= 1000. Test if there is any effect.
