Are Republicans just as likely as Democrats to display the American flag in front of their residence on the Fourth of July? 459 of the 687 Republicans surveyed display the flag on the Fourth of July and 396 of the 642 Democrats surveyed display the flag on the Fourth of July. What can be concluded at the a = 0.05 level of significance?

What can be concluded at the a = 0.05 level of significance?
e. Based on this, we should Select an answer the null hypothesis. f. Thus, the final conclusion is that ... O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the population proportion of Republicans who display the American flag in front of their residence on the Fourth of July is different from the population proportion of Democrats who display the American flag in front of their residence on the Fourth of July. The results are statistically insignificant at a = 0.05, so there is insufficient evidence to conclude that the population proportion of Republicans who display the American flag in front of their residence on the Fourth of July is different from the population proportion of Democrats who display the American flag in front of their residence on the Fourth of July. O The results are statistically insignificant at a = 0.05, so we can conclude that the population proportion of Republicans who display the American flag in front of their residence on the Fourth of July is equal to the population proportion of Democrats who display the American flag in front of their residence on the Fourth of July. The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the proportion of the 687 Republicans who displayed the American flag in front of their residence on the Fourth of July is different from the proportion of the 642 Democrats who displayed the American flag in front of their residence on the Fourth of July. g. Interpret the p-value in the context of the study. There is a 5.1% chance that Republicans and Democrats differ by at least 5.1% when it comes to displaying the American flag in front of their residence on the Fourth of July. If the sample proportion of Republicans who display the American flag in front of their residence on the Fourth of July is the same as
