Question 2 thetea247 | Meal Pl... Co. List of Sciences Olo... Research ECU D 14 pts A researcher tests the hypothesis that hyperactive children show more displays of anger during play than the typical child. The typical child (the general population) shows an average of μ= 3.3 displays of anger with a standard deviation of o=1.5. A sample of 36 hyperactive children show an average of = 4.1 displays of anger. Do hyperactive children show more displays of anger? Set alpha to a = .05 A. Is this a one or two tail test? (1 point) 1.1-tail 2. 2-tail B. Run the test in the steps below, but be consistent with your answer in Part A above! STEP 1: State the null and alternative hypotheses in words. Label HO and H1 (2 points) State the null and alternative hypotheses in symbols Label HO and H1 (2 points) STEP 2: Set up the criteria for making a decision (find the critical value). Be sure to use the proper sign for the value! (2 points) STEP 3: Compute the appropriate test-statistic. (4 points) Fail to Reject (1 point) Reject STEP 4: Evaluate the null hypothesis. STEP 5: (conclusion): What conclusion can you make based on STEP 4? (1 point) C. Based on your decision in Step 4 what type of error MIGHT you have made? (1 point) or
