In 1980 and again in 2010, a Gallup poll asked a random sample of 1000 US citizens people "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? State the null and alternative hypotheses: What is the sample statistic?
(you could also calculate the slope by just counting up how many units it goes up/down when you pick a point from the x-axis and move left/right. basically counting the rise over run)
