Question

Are Republicans just as likely as Democrats to display the American flag in front of their residence on the Fourth of July? 441 of the 695 Republicans surveyed display the flag on the Fourth of July and 521 of the 751 Democrats surveyed display the flag on the Fourth of July. What can be concluded at the αα = 0.10 level of significance?

For this study, we should use

The null and alternative hypotheses would be:

H1:H1: (Please enter a decimal)

The test statistic = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is αα
Based on this, we should the null hypothesis.
Thus, the final conclusion is that ...
- The results are statistically significant at αα = 0.10, 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 αα = 0.10, 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 αα = 0.10, so there is sufficient evidence to conclude that the proportion of the 695 Republicans who displayed the American flag in front of their residence on the Fourth of July is different from the proportion of the 751 Democrats who displayed the American flag in front of their residence on the Fourth of July.
- The results are statistically insignificant at αα = 0.10, 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.
