One evening, the manager asked the first 100 students entering the dining hall to answer the following question and 68% of them responded “No.” a) Who is the population for this sample survey? b) Who is the sample? c) Is the value 68% a statistic or a parameter? d) Explain how bias may have been introduced based on the way this convenience sample was selected AND suggest how the sample could have been selected differently to avoid that bias. e) Explain how bias may have been introduced based on the way the question was worded AND suggest how it could have been worded differently to avoid that bias.
