You will perform a Two Sample Hypothesis Test for Proportions. For the Hypothesis Test, make sure to report the following steps:

Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Find the critical value(s) and identify the rejection region(s). Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original claim.

In a random sample of 1276 U.S. adults, 903 favor using mandatory testing to assess how well schools are educating students. In another random sample of 1112 U.S. adults taken 9 years ago, 799 favored using mandatory testing to assess how well schools are educating students. At α = 0.05, can you support the claim that the proportion of U.S. adults who favor mandatory testing to assess how well schools are educating students is less than it was 9 years ago?
