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 379 randomly selected students who receive financial aid, 57 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 b. The null and altenative hypotheses would be: Hg: P (please enter a decimal) (Please enter a decimal) c. The test statistic (please show your answer to 3 decimal places.) d. The p-value - I e. The p-value is > ♥ f. Based on this, we should fail to reject 8. Thus, the final conclusion is that . O The data suggest the population proportion is not significantly lower than 18% at a (Please show your answer to 4 decimal places.) a the null hypothesis. 0.01, so there is sufficient evidence to conclude that the percentage of financial aid recipients who volunteer is equal to 18%. The data suggest the population proportion is not significantly lower than 18% at a 0.01, so there is insufficient evidence to conclude that the percentage of financial aid recipients who volunteer is lower than 18%. O The data suggest the populaton proportion is significantly lower than 18% at a 0.01, so there is sufficient evidence to conclude that the percentage of financial aid recipients who volunteer is lower than 18%.

Transcribed Image Text: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 379 randomly selected students who
receive financial aid, 57 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
b. The null and altemative hypotheses would be:
Họ: P
(please enter a decimal)
Hi: P
(Please enter a decimal)
c. The test statistic zv
(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 fail to reject
g. Thus, the final conclusion is that ...
a
the null hypothesis.
O The data suggest the population proportion is not significantly lower than 18% at a =
0.01, so there is sufficient evidence to conclude that the percentage of financial aid
recipients who volunteer is equal to 18%.
O The data suggest the population proportion is not significantly lower than 18% at a =
0.01, so there is insufficient evidence to conclude that the percentage of financial aid
recipients who volunteer is lower than 18%.
O The data suggest the populaton proportion is significantly lower than 18% at a =
0.01, so there is sufficient evidence to conclude that the percentage of financial aid
recipients who volunteer is lower than 18%.
