  1. Using a formula for a binomial proportion one-sample z-test with your data included, we have:
    z = .55 - .50 / √[(.50)(.50)/500] -->note: .55 is 275/500 in decimal form.
    Finish the calculation.

    Use a z-table to find the critical or cutoff value at 0.05 for a one-tailed test.

    If the z-test statistic calculated above exceeds the critical value from the z-table, reject the null. If the z-test statistic does not exceed the critical value from the z-table, do not reject the null.

    I hope this will help get you started.
