In 1980 and again in 2010, a Gallup poll asked a random sample of 1000 US citizens "Are you in favor of the death penalty for a person convicted of murder?" In 1980, the proportion saying yes was 0.66. In 2010, it was 0.64. Does this data provide evidence that the proportion of US citizens favoring the death penalty was higher in 1980 than it was in 2010? Use pi for the proportion in 1980 and p2 for the proportion in 2010. (1) State the null and alternative hypotheses: (2) What is the sample statistic? (3) A randomization distribution assuming the null hypothesis is true is shown. Which of the following is closest to the p-value?
