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.
Use the sample size and population proportion to determine the mean, up, of the sampling distribution of
sample proportions
