Math help! random samples and surveys?

Directions:you want to find out if a school bond issue for a new computer center is likely to pass in the next election. State whether each survey plan describes a good sample. Explain your reasoning.





5. You interview people coming out of a computer store in your town.





6. You choose people to interview at random from the city telephone book.





7. You interview every thent person leaving each voting place in your school district.











Those were the questions. i need help!!!!!

Math help! random samples and surveys?
7 would be the most accurate way but it is not very practical. It's not 5 because you would only be surveying people interested in computers. It's either 6 or 7. I pick 6. If it's wrong then argue with the teacher :)
