To test whether or not this value has since increased, a random sample of size 250 containers are weighed and found to have a sample mean of 17.2 kg. We will assume that the population of container weights is normally distributed with standard deviation of 5.4 kg. Problem 1 v Problem 2 V Test whether the mean population weight has increased at a level of significance of 0.5%. Show your relevant steps below. Problem 3 V Problem 4 V Step 1: Hypotheses: Problem 5 v . The null hypothesis Ho is (choose one): Problem Ou = 16.5 Of = 250.0 Of = 17.2 Ou =5.4 Problem 7 For the alternative hypothesis Ha we change the equal sign in Ho to (choose one): Problem 8 0 Step 2: Rejection Region: The rejection region is bounded by the following critical values: Critical z value(s) =[. (Enter critical values from lowest to highest. Leave second blank empty if there is only one critical value.) Step 3: Test Statistic: Standard Error = Calculated test statistic, z = (Keep at least five significant figures for all calculated intermediate values.) Step 4: Decision on HO: At a level of significance of 0.5% (choose one): O Reject Ho and accept Ha O Fail to reject Ho Step 5: Final
