Dr. Hughes researches the pattern of vending machine use on campus. He has found that two factors increase the use of vending machines (0-10) in college; one is time of the semester and one is time of day. He wants to determine if these two factors influence one another to form a more specific pattern of vending machine use. Dr. Hughes goes to several locations on campus to watch the use of vending machines. He records the time of day and the time within the semester. He later then transposes those times into groups (time of day 1=morning, 2=afternoon, 3=evening, 4=late night; time of semester 1=early, 2=late). 1. What are the researcher's independent and dependent variables? a. Independent: b. Dependent: 2. What are the null and alternative hypotheses (use the appropriate symbols not words)? a. H0: b. H1: 3. What is the appropriate test for the researcher to use? 4. Why is that statistic appropriate?
