The p-value = (Please show your answer to 4 decimal places.) The p-value is α Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly different from 20% at α = 0.10, so there is insufficient evidence to conclude that the percentage of financial aid recipients who volunteer is different from 20%. The data suggest the populaton proportion is significantly different from 20% at α = 0.10, 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 α = 0.10, so there is sufficient evidence to conclude that the percentage of financial aid recipients who volunteer is equal to 20%.
