Graphical Analysis, In Exercises 9, the graph of a population distribution is shown with its mean and standard deviation. Random samples of size 100 are drawn from the population. Determine which of the figures labeled (a)-(c) would most closely resemble the sampling distribution of sample means. Explain your reasoning.
