Consider the following hypothesis test. Ho: # $ 50 Ha: A > 50 A sample of 60 is used and the population standard deviation is 8. Use the critical value approach to state your conclusion for each of the following sample results. Use a = 0.05. (Round your answers to two decimal places.) (a) * = 52.1 Find the value of the test statistic. 2.03 State the critical values for the rejection rule. (If the test is one-tailed, enter NONE for the unused tall.) test statistic s test statistic > State your conclusion. Do not reject Ho. There is sufficient evidence to conclude that > > 50. Reject Ho. There is sufficient evidence to conclude that # > 50. O Do not reject Ho. There is insufficient evidence to conclude that , > 50. Reject Ho. There is insufficient evidence to conclude that , > 50. (b) * = 51 Find the value of the test statistic. 0.97 State the critical values for the rejection rule.
