According to a Gallup poll in 2006, about 10% of Americans said they were "very afraid" of flying on an airplane.
Suppose that we took random samples of n = 40 people from this population and computed the proportion of
people in each sample who were very afraid of flying.
Which of the following distributions is the best approximation of the sampling distribution of the proportion of
people who were very afraid of flying?
Each distribution uses the same scale.
