Hypothesis. testing. The process of making judgments about a large group (population) on the basis of a small subset of that group (sample) is known as statistical inference.. Hypothesis testing, one of two fields in statistical inference, allows us to objectively assess the probability that statements about a population are true. . 4’10” 4’11” 5’0” 5’1” 5’2” 5’3” 5’4” 5’5” 5’6” 5’7” 5’8” 5’9” 5’10” 5& and. . t. . - tests .

Sections 12.1 to 12.4. • Formulate null and alternative hypotheses correctly based on the context of a testing situation.. • Distinguish between a one-sided and two-sided alternative hypothesis.. Textbook: Sections 12.3 to 12.4. • Frame a 2x2 test of independence as a test of difference of two proportions. • Apply ideas of forming hypotheses, calculating test statistics, and calculating p-values..
