Understanding how the 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 0.10 for the level of significance for the two-tailed test. For each potential choice for the level of significance, find the critical values. Round your answers to three decimal places. Critical values at a = 0.01: Critical values at a = 0.05: Critical values at a=0.10: Scratch work (Not graded) Standard Normal Distribution Step 1: Select one-tailed or two-tailed. O One-tailed OTwo-tailed Step 2: Enter the critical value(s). (Round to 3 decimal places.) Explanation Check and and and 0 (b) After choosing the level of significance, the researcher takes a sample and finds that the value of the test statistic is z=-1.727. For which of the levels of significance would the null hypothesis be rejected? Choose all that apply. α=0.01 a=0.05 a=0.10 None of the above X 2022 McGraw Hill LLC. All Rights Reserved.
