Assume that the sampling was done with 3000 random people in 2012 and 3000 random people in 2004. How many of the people in 2012 and how many of the people in 2004 said they strongly favored gay marriage? Answer: 0.47 x 3000 = 1410 people strongly supported gay marriage in the 2012 sample, and only 0.31 x 3000 = 930 in the 2004 sample. Verify that the conditions for using the two-proportion confidence interval have been met
