Find the test statistic. 1) Find the critical value for 1) 5) You wish to test the 5) a two-tailed test with a = Ha: ju > 6 at a level of 0.01 and n - 38. significance of a - 0.05 and are given sample statistics n - 50, x - 6.3, and o - 1.2. Compute the value of the standardized test statistic. 2) Find the critical value for 2) 6) Find the standardized test 6) a left-tailed test with a = statistic for a sample with 0.025 and n - 16. n - 12, x = 30.2, s = 2.2, and a = 0.01 if Ha: H> 29. 3) Find the critical values for 3) . in a sample with n = 20 and 7) Find the standardized test 7) a =0.10 if Ha: H x8. statistic for a sample with n = 10, x = 7.9, s = 1.3, and a = 0.05 if Ha: H = 8.8. 4) Determine the critical 8) Determine the 8) value about the standardized test statistic population proportion for the population Ha: p * 0.325 given n = 42 proportion Ha: p x 0.325 and p = 0.247. Use given n = 42 and a = 0.05. P = 0.247. Use a = 0.05
