A USU Today survey found that of the gun owners surveyed 55% favor stricter gun laws. The survey
Involved 500 gun owners. Test the claim that a majority (more than 50%) of gun owners favor stricter gun laws. Use a .05 significance level.

1. Using a formula for a binomial proportion one-sample z-test with your data included, we have:
z = .55 - .50 / √[(.50)(.50)/500]
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.
