1 A research organization recently issued a statement suggesting that 65% of American voters are dissatisfied with the work of Congress. You designed a simulation to generate sample data to reflect this proportion. An automated random number sample program is used that has a sample of size 20, is run 100 times, and uses the numbers 1 through 13 to represent dissatisfied voters and the numbers 14 through 20 to represent satisfied voters. The dot plot below represents the outcome of the simulation, with the margin of error displayed.
