Inference aplet 9-3
If you choose one of the hypothesis tests, you can choose the
alternative hypothesis to test against the null hypothesis. For
each test, there are three possible choices for an alternative
hypothesis based on a quantitative comparison of two
quantities. The null hypothesis is always that the two
quantities are equal.Thus, the alternative hypotheses cover the
various cases for the two quantities being unequal: <, >, and .
In this section, we will use the example data for the Z–Test on
1 mean to illustrate how the aplet works and what features the
various views present.
