The mayor of a town believes that over 70% of the residents favor construction of a new bridge. Is there sufficient evidence at the 0.10 level to support the mayor's claim? After information is gathered from 420 voters and a hypothesis test is completed, the mayor decides to reject the null hypothesis at the 0.10 level. What is the conclusion regarding the mayor's claim? Is there sufficient evidence or not?
