Please help me with this math homework problem?

The report of a study of seat belt use by drivers says, "Hispanic drivers were not significantly more likely than White/non-Hispanic drivers to overreport safely belt use (27.4 vs 21.1%, respectively; z= 1.33, P> 1.0)" How do you know that the P-value given is incorrect? What is the correct one-sided P-value for the test statistic z=1.33?
