1. For each of the following, state whether you'd use one-sample or two-sample procedures to analyze the data, and explain why. A. A university is interested in whether there's a difference between students who live on campus and students who live off campus with respect to absenteeism. Over one semester, researchers take random samples of on-campus and off-campus students and record the number of classes each student misses. (1 point) B. A company wants to know whether listening to music improves efficiency among its employees. Two employees are randomly chosen from each of 10 departments and are given the same task to complete. One employee from each pair is allowed to listen to music and the other employee isn't. Researchers record the time it takes each employee to complete the assigned task. (1 point) 1.) 4.) The university is interested in whether there's a difference between students who live on campus and students who live off campus with respect to absenteeism, we would use a two-sample procedure to analyze the data. This is because We are comparing two independent groups (on-campus students cincl off-campus students) and we want to determine whether there is a statistically significant difference between their mean number of absences over one semester. By using a two-sample procedure, we can compare the means of the two groups and cletermine whether any difference between them is statistically Significant. b.) The company wants to know whether listening to music improve efficiency among its employees, we would use a two-sample procedure to analyze the data. In this case, the researchers randomly selected two employees from each of 10 departments and assigned them the same task to complete. One employee was allowed to listen to music while the other employee was not. By measuring the time it took each employee to complete the task, the researchers Could compare the mean completion times of the two groups - those who listened to music and those who did not). A two-sample procedure would be used to determine whether any difference between the means of the two groups is statistically significan
