Provide an appropriate response. Construct a 95% confidence interval for p1 - p2 for a survey that finds 30% of 240 males and 41% of 200 females are opposed to the death penalty. (-1.532, 1.342) (-1.324, 1.512) (-0.200, -0.021) (-0.561, 0.651)

Let p equal the proportion of Americans who favor the death penalty. If a random sample of n = 1230 Americans yielded y = 861 who favored the death penalty, find an approximate 95% confidence interval for p.

Use the given sample data and confidence level. In each case, (a) find the best point estimate of the population proportion p; (b) identify the value of the margin of error E; (c) construct the confidence interval; (d) write a statement that correctly interprets the confidence interval. From a Prince Market Research poll in which respondents were asked if they acted to annoy a bad driver: $n = 2518 , x = 1083$ who said that they honked. Use a $90\%$ confidence level.
