Q6.3 2 Points We used R to calculate a 98% confidence interval for the difference between the proportion of those who identify as Democrat or lean Democrat who think that it is important to see a person's political affiliation on their dating profile and the proportion of those who identify as Republican or lean Republican who think that it is important to see a person's political affiliation on their dating profile. The 98% confidence interval is (0.097, 0.263). Here is an interpretation of the confidence interval: We estimate, with 98% confidence, that the proportion of those who identify as Democrat or lean Democrat who think that it is important to see a person's political affiliation on their dating profile is between 0.097 and 0.263 [higher/lower] than the proportion of those who identify as Republican or lean Republican who think that it is important to see a person's political affiliation on their dating profile. Which word makes the interpretation correct? O lower O higherQ6 Political Affiliation on Dating Profiles 8 Points According to a recent poll by the Pew Research Center, 53% of those who have used dating sites/apps over the past year report that it is important to see a person's political affiliation on their dating profile.

Of the 268.respondents who identify as Republican or lean Republican, 107 think that it is important to see a person's political affiliation on their dating profile. Q6.1 2 Points Assume that the independence conditions for constructing a confidence interval are met. Since the observed number of successes and failures in each sample are at least 10, we have met the remaining condition to construct a confidence interval. O True O FalseQ6.2 2 Points Which of the following is the point estimate for the difference between the proportion of those who identify as Democrat or lean Democrat who think that it is important to see a person's political affiliation on their dating profile and the proportion of those who identify as Republican or lean Republican who think that it is important to see a person's political affiliation on their dating profile? O 0.399 O 0.579 O 0.489 O 0.180Q6.4 2 Points Recall that the 98% confidence interval is (0.097, 0.263). Using only this confidence interval (i.e., do not conduct a hypothesis test), do the data suggest that there is a difference between the proportion of those who identify as Democrat or lean Democrat who think that it is important to see a person's political affiliation on their dating profile and the proportion of those who identify as Republican or lean Republican who think that it is important to see a person's political affiliation on their dating profile?
