Your town is deciding whether to build a new park. A sample of 100 people are asked if they would vote yes or
no to the new park. The survey results are shown on the
table. The mayor estimates that half of the people who said
they are undecided will actually vote "yes". Assume that the
mayor is correct. The town has 1,000 voters. How many
voters will say yes to building the park?
