Question

1.YouGov conducted a survey of US residents for CBS News between September 26 and 28, 2017, concerning views on football players protesting by kneeling during the national anthem. From the random selection, 413 were Democrat, and 299 were Republican; 50 of the Democrats disapproved of football players taking a knee, whereas 203 of the Republicans disapproved.† Part 1 of 3 Find a 95% confidence interval for the difference in the proportions who disapprove of kneeling during the national anthem between the Republicans and the Democrats. (Note that sample sizes are sufficiently large. Use (Republican) − (Democrat). Use a table or technology. Round your answers to three decimal places.) Does the confidence interval support the belief that the proportion who disapprove of kneeling during the national anthem is different for Republicans and Democrats? Why or why not?

2.Based on a survey of 3,019 adults, you can be 95% confident that between 39.2% and 42.8% of Americans dip into their savings at least once a month.What is the point estimate and margin of error for this confidence interval? Were the conditions met for a confidence interval of a population proportion? (Round your answers to three decimal places.)
