In a random sample of 1008 U.S. adults taken 10 years ago, 515 think that the U.S. government is doing too little to protect the environment. In a recent random sample of 1022 U.S. adults, 480 think that the U.S. government is doing too little to protect the environment. At ? = 0.05, test the claim that the proportion of U.S. adults who think that the U.S. government is doing too little to protect the environment has changed?

Create a 95% confidence interval to estimate the difference between the proportion of U.S. adults who think the U.S. government is doing too little (you don’t need to interpret the interval, just list it to 3 decimal places)

Does the confidence interval verify the results from the hypothesis test? Why?

Ten years ago, a random sample of 257 dog owners was taken and it was found that 146 owned more than one dog. Recently, a random sample of 380 dog owners showed that 200 owned more than one dog.
