Understanding how the choice of a level of significance... (Espanol) A researcher is going to perform a two-tailed hypothesis test. The test statistic will follow a standard normal distribution. Answer parts (a) and (b) below. You may use the tool below in the scratch work area to help you. Your work with the tool will not be graded. (a) The researcher might choose 0.01, 0.05, or (b) After choosing the level of significance, the 0.10 for the level of significance for the two- researcher takes a sample and finds that the tailed test.
