A newspaper conducted a statewide survey concerning the 1998 race for state senator. The newspaper took a simple random sample of n = 1300 registered voters and found that 670 would vote for the Republican candidate. Let p represent the proportion of registered voters in the state who would vote for the Republican candidate. We test a null hypothesis of p = .50 against an alternative hypothesis of p > .50.

(b) What is the P-value of the test?
