What is the decision for this hypothesis test?
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%? Let α = 0.05.

What is the decision for this hypothesis test?
Reject the null because the test statistic is in the critical region and the p-value is greater than alpha.
Fail to reject the null because the test statistic is not in the critical region and the p-value is greater than alpha.
Reject the null because the test statistic is not in the critical region and the p-value is less than alpha.
Fail to reject the null because the test statistic is in the critical region and the p-value is greater than alpha.
