+20 A research organization recently issued a statement suggesting that 80% 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 50, is run 100 times, and uses the numbers 1 through 16 to represent dissatisfied voters and the numbers 17 through 20 to represent satisfied voters. The dot plot below represents the outcome of the simulation, with the margin of error displayed.
Using the data from this simulation, what is the sample mean (rounded to the nearest tenth), and approximately what proportion of voters are dissatisfied?
39.6 and approximately 79.2% of voters are dissatisfied with Congress
39.8 and approximately 79.6% of voters are dissatisfied with Congress
39.9 and approximately 79.8% of voters are dissatisfied with Congress
4.0 and approximately 80.0% of voters are dissatisfied with Congress
