A research organization has recently issued a statement suggesting that 30% of American mothers are unhappy with their children's work habits. You have designed a simulation to generate sample data refuting this claim. An automated random number program is used that has sample of size 20, is run 100 times, and uses the numbers 1 through 6 to represent unhappy mothers, and the numbers 7 through 20 to represent happy mothers. The dot plot below represents the outcome of the simulation.



Using the data from this simulation, rounded to the nearest whole person, what is the average number of mothers out of 20 who are unhappy with their children's work habits?
