Question: The mayor and city council in a certain jurisdiction want to reduce the average waste of their residential households. Results in other jurisdictions suggest the average weight of garbage per household, where there is a weekly pickup cycle, is 22 kg with a standard deviation of 7 kg. They want to run an experiment in which they monitor the weight of the refuse from approximately 100 randomly selected homes following the introduction of a program designed to divert waste to recycling alternatives. If the program is a success, they would like to broaden the experiment for the entire city. Discuss the specific hypotheses they might wish to test if their goal is to come up with conclusions having practical implications. What other information might be useful?
