Suppose that you are conducting a test to see if the mean time that an 8-12 year old child spends watching TV a day is greater than 3.2 hours. You collect a sample of 55 children and find a sample mean of 3.7 hours with a sample standard deviation of 1.3 hours. The significance level for this test is .01. Hypothesis test results: Mean Sample Mean Std. Err. DF Test-Stat P-value 3.7 0.17529196 54 2.8523840.0031 The critical value for this test is 2.397. Use the critical value method to do the following. Write the answer in 3 or 4 complete sentences. Answers not in complete sentences will be deducted 2 points.: 1. Determine if we should reject or fail to reject the null hypothesis. 2. Explain why you are rejecting or failing to reject the null hypothesis. 3. Write the conclusion for the test. Make sure that you identify the variable that is being tested.
