**MathGuru**, Friday, July 13, 2012 at 7:15pmYou can use a one-sample proportional z-test for your data. (Test sample proportion = 39/90 and sample size = 90) Convert fractions to decimals to use in the z-test. Find the critical value in the appropriate table at .05 level of significance for a two-tailed test. Compare the test statistic you calculate to the critical value from the table. If the test statistic exceeds the critical value, reject the null. If the test statistic does not exceed the critical value, do not reject the null. You can draw your conclusions from there.
