A USU Today survey found that of the gun owners surveyed 275 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.

*Must provide calculator function, H0, H1, critical value (or values), test value, Decision- Reject or failure to reject?, conclusion-agree or disagree?*

Which calculator function ?

H0:

H1:

Critical value :

Test value :

Decision :

Conclusion:

Please include all , since it is part of the problem!

Explanation / Answer

Ho = p = 0.5

H1 = p>0.5

the significance levl = 0.5'therefore the critical region fro the z table = z>1.96

the p = 275/500 = 0.55

z stat = (0.55-0.50)/sqrt(0.50^2/500) = 2.24

since z= 2.24>1.96

therefore we will reject the null hypothesis
