Select an answer the null hypothesis.
O The data suggest the populaton proportion is significantly lower than 18% at a = 0.05, so there
is sufficient evidence to conclude that the percentage of financial aid recipients who volunteer
is lower than 18%.
O The data suggest the population proportion is not significantly lower than 18% at a = 0.05, 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 population proportion is not significantly lower than 18% at a = 0.05, so
there is sufficient evidence to conclude that the percentage of financial aid recipients who
volunteer is equal to 18%.
