In a 2009 nonscientific poll on www.ESPN.com, 67% of the respondents believed that Roger Federer was going to defeat Andy Roddick in the 2009 Wimbledon Gentlemen’s singles championship. Suppose that a survey of 150 tennis fans conducted in Europe at the same time resulted in 118 who believed that Federer was going to win. Perform a hypothesis test to determine if it is reasonable to conclude that the percentage of all European tennis fans who believed that Federer was going to win the 2009 championship was higher than 67%, the result in the ESPN.com poll. Use a 2% significance level and both the p-value and the critical-value approaches.
