21. fail to reject
22. the null hypothesis.
23. Thus, the final conclusion is that ...

• The data suggest the population proportion is notsignificantlydifferent from 16% at
• = 0.10, so there is statistically significant evidence to conclude that the percentage of registered voters who will vote in the upcoming election will be equal to 16%.
• The data suggest the population proportion is notsignificantlydifferent from 16% at
• = 0.10, so there is statistically insignificant evidence to conclude that the percentage of registered voters who will vote in the upcoming election will be different from 16%.
• The data suggest the populaton proportion issignificantlydifferent from 16% at
• = 0.10, so there is statistically significant evidence to conclude that the the percentage of all registered voters who will vote in the upcoming election will be different from 16%.
