QUESTION 10 The quality control manager wants to know whether the filling machines in the production line are, on average, overfilling the 75-gram bags of lollies. She randomly samples 100 bags from the production line, measures their weight, and computes the sample mean and sample standard deviation, and uses the sample result to conduct a hypothesis test. Depending on the results of the test, she makes a decision on whether or not to shut down the production line to adjust the settings on the filling machines. Based on the question asked by the quality control manager, the alternative hypothesis HA is formulated as: Oa. HA: H = 75. Ob. HA: H 75 . O d. HA: H > 75.QUESTION 13 The rejection region for testing the hypotheses, Ho : H = 80 HAH 1.96 O b. z-1.65 O d. z 75 . O d. Ho: H > 75.QUESTION 4 In testing the hypotheses: Ho : H = 35 HA : H
