| Description | H0: μ1 = μ2 We are really testing our sample data 1X = 2X and inferring that these data are representative of the population μ1 = μ2, allowing for a certain amount of error in our decision. The alternative hypothesis is either accepted or rejected based upon the decision about the hypothesis under test. Thus, an inference can be defined as any conclusion that is drawn from a statistical evaluation. Statistics from our sample provide us with a basis for estimating the probability that some observed difference between samples should be expected due to sampling Table 8.1 Examples of Null Hypotheses Chapters Statistical Tests Null Hypothesis 9 Two-sample t-test µ1 = µ2 or µ1 - µ2 = 0 9 Paired t-test µd = 0 10 One-way analysis of variance µ1 = µ2 = µ3 =…µk 13 Correlation rxy = 0 14 Linear regression No linear regression 16-18 Tests of association No association 21 Nonparametric tests Same population error. Two approaches could be used: 1) create a confidence interval or 2) establish a ratio and compare the resultant test statistic to a predetermined critical value. The former has already been employed in the previous chapter, with the establishment of a confidence interval for a population parameter based on sample results.
