20% of all college students volunteer their time. Is the percentage of college students who are volunteers different for students receiving financial aid? Of the 352 randomly selected students who receive financial aid, 49 of them volunteered their time. What can be concluded at the oa = 0.01 level of significance? a. For this study, we should use z-test for a population proportion v b. The null and alternative hypotheses would be: Ho: vlSelect an answer V (please enter a decimal) H: ? v Select an answer v (Please enter a decimal) c. The test statistic ? v (please show your answer to 3 decimal places.)

Question
20% of all college students volunteer their time. Is the percentage of college students who are volunteers
different for students receiving financial aid? Of the 352 randomly selected students who receive financial
aid, 49 of them volunteered their time. What can be concluded at the a 0.01 level of significance?
a. For this study, we should use z-test for a population proportion V
b. The null and alternative hypotheses would be:
Ho:
Select an answer
(please enter a decimal)
Select an answer V
(Please enter a decimal)
C. The test statistic
(please show your answer to 3 decimal places.)
d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is ? v
f. Based on this, we should Select an answer v the null hypothesis.
g. Thus, the final conclusion is that
The data suggest the populaton proportion is significantly different from 20% at a = 0.01, so
there is sufficient evidence to conclude that the percentage of financial aid recipients who
volunteer is different from 20%.
The data suggest the population proportion is not significantly different from 20% at a = 0.01,
so there is sufficient evidence to conclude that the percentage of financial aid rcipients who
volunteer is equal to 20%.
O The data suggest the population proportion is not significantly different from 20% at a = 0.01,
so there is insufficient evidence to conclude that the percentage of financial aid recipients
who volunteer is different from 20%
