1] We have learned two inferential statistics at this point of the semester. a) What are their names? Z-test, Sign test, and also linear regression h) What do they have in common? Sign tests and z-tests both give inferences of a based on a population based on a sample. The},r both use a critical value, a obtained value, and an alpha like any inferential statistic. c) What makes them different from one another? Sign test show effects of only two binomial variables, but they do not show the magnitude of those effects. Ztests don't show effects as clear and cut, but the}? show them in more detail, and are overall more useful as a statistical tests
