19% of all college students volunteer their time. Is the percentage of college students who are volunteers
different for students receiving financial aid? Of the 380 randomly selected students who receive financial aid,
49 of them volunteered their time. What can be concluded at the a = 0.05 level of significance?

d. The p-value =

e. The p-value is ?
f. Based on this, we should
O the null hypothesis.
Select an answer
g. Thus, the final conclusion is that ...
OThe data suggest the population proportion is not significantly different from 19% at a = 0.05, so
there is insufficient evidence to conclude that the percentage of financial aid recipients who
volunteer is different from 19%.
OThe data suggest the populaton proportion is significantly different from 19% at a = 0.05, so there
is sufficient evidence to conclude that the percentage of financial aid recipients who volunteer is
different from 19%.
OThe data suggest the population proportion is not significantly different from 19% at a = 0.05, so
there is sufficient evidence to conclude that the percentage of financial aid recipients who volunteer
is equal to 19%.
