18% of all college students volunteer their time. Is the percentage of college students who are volunteers smaller for students receiving financial aid? Of the 313 randomly selected students who receive financial aid, 47 of them volunteered their time. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use z-test for a population proportion ✓ b. The null and alternative hypotheses would be: Ho: P H₁: pv c. The test statistic d. The p-value = 0.18 0.18 (please enter a decimal) ✓(Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.)
