QUESTION 3 The quality control manager wants to know whether the filling machines in the production line are, on average, overfilling the 75gram bags of lollies.

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 null hypothesis H0 is formulated as: O a\"H0:;1=75. O b-H0: p75. O d-H0:;l>75. In testing the hypotheses: H0 : ,u = 35 HAzy75. O d-HA2;1>75
