2016, 535 adults aged 18 years old or older were asked if they think that there is some form of life on other planets in the universe or not (Group 1). Of the 535 surveyed, 326 said yes. When the same question was asked in 2006, 385 of the 500 individuals surveyed said yes (Group 2). Construct a 90% confidence interval for the difference between those in 2006 and 2016 who believe there is life on other planets.
