Satisfied? A 2010 poll asked people in the United States whether they were satisfied with their financial situation. A total of 301 out of 1156 people said they were satisfied. The same question was asked in 2012 , and 338 out of 832 people said they were satisfied. Part: 0 / 2 0 of 2 Parts Complete Part 1 of 2 (a)Construct a 99% confidence interval for the difference between the proportions of adults who said they were satisfied in 2012 and 2010 . Let p1 denote the proportion of individuals satisfied with their financial situation in 2012 and p2 denote the proportion of individuals satisfied with their financial situation in 2010 . Round the answers to three decimal places. A 99% confidence interval for the difference between the proportions of adults who said they were satisfied in 2012 and 2010 is <p1-p2< .
