Some researchers claim that herbal supplements such as ginseng or ginkgo biloba enhance human memory. To test this claim, a researcher selects a sample of n= 36 college students. Each student is given a ginkgo biloba supplement daily for six weeks and then all the participants are given a standardized memory test. For the population, scores on the test are normally distributed with u = 70 and o = 15. The sample of n= 36 students had a mean score of M = 78. a. Are the data sufficient to that the herb has a significant effect on memory? Use a two-tailed test with a = .05. You must label and indicate an answer for all 4 steps of the hypothesis test.
