16% of all college students volunteer their time. Is the percentage of college students who are volunteers larger for students receiving financial aid? Of the 377 randomly selected students who receive financial aid, 72 of them volunteered their time. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ?v Select an answer (please enter a decimal) H: ? v Select an answer v (Please enter a decimal) c.
