Question

Historically, the percentage of U.S. residents who support stricter gun control laws has been 52%. A recent Gallup Poll of 1011 people showed 495 in favor of stricter gun control laws. Assume the poll was given to a random sample of people. Test the claim that the proportion of those favoring stricter gun control has changed. Perform a hypothesis test, using a significance level of 0.05. See page 405 for guidance. Choose one of the following conclusions:
i. The percentage is not significantly different from 52%. (A significant difference is one for which the p-value is less than or equal to 0.050.)
ii. The percentage is significantly different from 52%.
