A research organization recently issued a statement suggesting that 75% 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 40, is run 100 times, and uses the numbers 1 through 15 to represent dissatisfied voters and the numbers 16 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

A) x bar equals 30.1 and approximately 75.3% of voters are dissatisfied with Congress
B) x bar equals 29.5 and approximately 73.8% of voters are dissatisfied with Congress
C) x bar equals 29.6 and approximately 74.0% of voters are dissatisfied with Congress
D) x bar equals 29.8 and approximately 74.5% of voters are dissatisfied with Congress
