Lab B (Chi-square)
Law school students and other students at a university are asked to complete a survey. The researcher knows the proportion of law students at the university [ p(Lawyers) ]. She wonders if the number of lawyers who complete the survey [ Obs(Lawyers) ] versus other students [ N - Obs(Lawyers) is what one would expect given this N and proportion of law students. Use the chi-square goodness of fit test to assess whether observations are consistent or inconsistent with expectations. In your response to the questions, use the information for Problem a in the data set number assigned to you by the teaching assistant.
Another researcher sends out surveys to students in the engineering school and the law school. She counts the number of survey-completers from each school who are male versus female, and wonders whether gender and school are related. In your response to the questions, use the information for Problem b in the data set number assigned to you by the teaching assistant.
