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.

Using a formula for a binomial proportion onesample ztest with your data included, we have:
z = .55  .50 / √[(.50)(.50)/500]
Finish the calculation.
Use a ztable to find the critical or cutoff value at 0.05 for a onetailed test.
If the ztest statistic calculated above exceeds the critical value from the ztable, reject the null. If the ztest statistic does not exceed the critical value from the ztable, do not reject the null.
I hope this will help get you started.
