# One of the more popular statis

One of the more popular statistics reported in the media is the​ president’s job approval rating. The approval rating is reported as the proportion of the population who approve of the job that the sitting president is doing and is typically based on a random sample of registered voters where the sample size is the same week to week. Complete the questions below.
A poll showed the approval rating to be 0.48 ​(48​%). A second poll based on 2500 randomly selected voters showed that 1260 approved of the job the president was doing. Do the results of the second poll indicate that the proportion of voters who approve of the job the president is doing is significantly higher than the original​ level? Explain. Assume the

α=0.1 level of significance. Find the null and alternative hypothesis, the test statistic, the p-value, and whether to reject the null hypothesis.
