How to find the p-value with only the null and alternative hypothesis and test stat given?

"In a test of Ho: u = 90 against Ha: u %26gt; 90, the sample data yielded the test statistic z=2.34. Find the p-value for the test."





How do I do this?





Thank you|||2.34 corresponds to a value of approximately of p = 0.9904 (or 99.04%).





Note: we assume standard normal unless told otherwise.
