8.1 - Using the information below, conduct a hypothesis test using the 4-step approach: Ho: H = 25 Ha: H # 25 n= 57 a= .01 x=28.1 0 =8.46 Step 1 - State the hypothesis (already done for you...see above). Will this be a one-tailed or a two-tailed test? Step 2 - Set the criteria for a decision. Will this be a z-test or a t-test? Step 3 - Compute the test statistic. Step 4 - Make a decision.8.2 - Using the information below, conduct a hypothesis test using the 4-step approach: Ho: H = 36 Ha: H # 36 n= 51 a=.01 x= 38.4 s = 5.93 Step 1 - State the hypothesis (already done for you...see above). Will this be a one-tailed or a two-tailed test? Step 2 - Set the criteria for a decision. Will this be a z-test or a t-test? Step 3 - Compute the test statistic. Step 4 - Make a decision.8.3 - Using the information below, conduct a hypothesis test using the 4-step approach: Ho: H = 7.48 Ha: H
