Dr. Nick Rivierа clаims thаt herbal supplements such as ginseng оr ginkgо bilоba enhance human memory. To test this claim, he selects a sample of n = 144 adults. Each participant takes a ginkgo biloba supplement daily for six weeks. After the six weeks, all participants are given a standardized memory test. Scores on the test are normally distributed with μ = 95 and σ = 18 for the population. The sample of n = 144 adults had a mean score of M = 99. Are the data sufficient to that the herb has a significant effect on memory? Use a two-tailed test with α = .05.
