Of the 381 randomly selected students who receive financial aid, 34 of them volunteered their time. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: H₁: ✓ Select an answer ?✓ Select an answer ✓ c. The test statistic ? ✓ = (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) d. The p-value= e. The p-value is ? ✓ α f. Based on this, we should [Select an answer the null hypothesis. g. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) O The data suggest the population proportion is not significantly lower than 12% at a = 0.05, so there is insufficient evidence to conclude that the percentage of financial aid recipients who volunteer is lower than 12%. The data suggest the population proportion is not significantly lower than 12% at x = 0.05, so there is sufficient evidence to conclude that the percentage of financial aid recipients who volunteer is equal to 12%. O The data suggest the populaton proportion is significantly lower than 12% at a = 0.05, so there is sufficient evidence to conclude that the percentage of financial aid recipients who volunteer is lower than 12%.
