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.

Question
![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.
The markers along the horizontal axis are one
standard error apart, with the center at the
mean. Use the sample size and population
proportion to determine the standard error
first. Round the standard error to 3 decimal
places, and then select the correct values for
the markers from the choices provided.
Starting from the left,
three standard
errors below the
mean
two standard errors
below the mean
