A researcher is looking at the effect if over the counter cold medication has an effect on mental awareness. In the general population mental awareness scores are generally distributed with u = 60 and o = 8. She takes a sample from this population of n = 16 and gives them the drug and finds that the mean mental awareness score for this group is M = 56.5. Set alpha =.05 and test the hypothesis that the drug affects mental awareness. Use a two-tailed test. Show all four steps.
