___________ is composed of the extreme sample values that are very unlikely to be obtained if the null hypothesis is true.

Dr. Nick Riviera claims that herbal supplements such as ginseng or ginkgo biloba 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.

A hypothesis is a statement about a _________________; ________________ data is used to test this hypothesis.
