Shortly after September 11th 2001, a researcher wanted to determine if the proportion of females that favored war with Iraq was significantly different from the proportion of males that favored war with Iraq. In a sample of 71 females, 26 favored war with Iraq. In a sample of 57 males, 42 favored war with Iraq.

What is the P-value for the test? Give your answer to four decimal places.

I have found that the test statistic is -4.1759. The formula for the p-value is P(|Z| > |TS|)=2(1-Φ(|TS|)). The problem I have is that I do not know how to find Φ(4.1759). My Z-table only goes up to 3.9. So can someone help please?
