A 2019 Pew Research poll found that 73% of U.S. adults believe that the economic gap between the rich and poor in the United States will widen over the next 30 years. The survey assessed whether Americans feel optimistic or pessimistic about the country's future. Let's assume that 0.73 is the population proportion. Suppose random samples of 150 U.S. adults are randomly selected.
