An estimated 78.1% of U.S. households had high-speed internet connection in 2013. A researcher wants to test this claim in his area because he believes that the estimate should be much higher. In a random sample of 510 households it was found that 408 had high-speed internet connection. Is there evidence to show that the percentage of U.S. households in this researcher's area with high-speed internet connection is greater than 78.1% ?
