Document Summary
Bio 2244b- textbook notes chapter 7: 7-1, 7-2, 7-3, 7-5. Hypothesis: a claim or statement about a property of a population. Hypothesis test (test of significance): a standard procedure for testing a claim about a property of a population. Recall the rare event rule: if, under a given assumption, the probability of a particular observed event is exceptionally small, we conclude that the assumption is probably not correct. Components of a formal hypothesis test: null hypothesis (h0): a statement that the value of a population parameter (such as proportion, mean, or standard deviation) is equal to some claimed value. Critical region (rejection region): the set of all values of the test statistic that cause us to reject the null hypothesis. Tails: the extreme regions in a distribution that are bounded by critical values: two-tailed test: the critical region is in the two extremes of the regions (tails) under the curve.
