There is one more variable in the dataset that we have not used yet named ‘Volunteer’. This variable is the number of hours our sample of college student participants spent volunteering at a local shelter per week. I hypothesize that college students volunteer more than the general population and we happen to have population data to test this hypothesis! The number of hours the general population volunteers is 2 hours per week.
Use this information to help me test my hypothesis by conducting the appropriate test and then answer the following questions:
