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.
(a) Determine the critical value(s) for a right-tailed test of a population mean at the α=0.05 level of significance with 10 degrees of freedom. (b) Determine the critical value(s) for a left-tailed test of a population mean at the alphaαequals=0.01level of significance based on a sample size of n=20. (c) Determine the critical value(s) for a two-tailed test of a population mean at the α =0.10 level of significance based on a sample size of n=16.
