I. Find the critical values using a significance level of a = .05. Do we fail to reject Ho or reject Ho? 1. p. 272 #21 Critical Value Write reject Ho or fail to reject Ho. 2. p, 272 #22 Critical v Write reject Ho or fail to reject Ho. 3. p,272 #23 Critical value Write reject Ho or fail to reject Ho . 4. p. 272 #24 Critical value Write reject Ho or fail to reject Ho. Il. Use the handout on p.2 in the first file under Module 6 in Canvas to do the following. 1. p. 383 #12 1. Ho: HA : 2. a = 3. Reject Ho if z. or z_ 4. Write the formula for the test statistic and plug in the values. The value of the test statistic is z =_ 5. a. Draw the normal distribution. b. Shade the rejection region (s). c. Label the z-axis with the critical value(s) and the value of the test statistic. Draw a vertical line with an arrow on the z-axis to indicate where the value of the test statistic lies. d. Write reject Ho or fail to reject Ho
