Calculate a critical z-score for a left-tailed, right-tailed, or two-tailed test.
How to Find a Critical Z Value LEARNING OBJECTIVE: Calculate a critical z-score for a left-tailed, right-tailed, or two-tailed test. Select the correct statement. a.) The critical z-score for a left-tailed test at a 12% significance level is -0.45. b.) The critical z-score for a right-tailed test at a 9% significance level is 1.34. c.) The critical z-score for a two-sided test at a 4% significance level is 1.75. d.) The critical z-score for a two-sided test at a 20% significance level is 0.85.
