The graph of the waiting time (in seconds) at a red light is shown below on the left with its mean and standard deviation. Assume that a sample size of 100 is drawn from the population. Decide which of the graphs labeled (a)-(c) would most closely resemble the sampling distribution of the sample means. Explain your reasoning.

Graph V most closely resembles the sampling distribution of the sample means, because u; =.0; =, and the graph (Type an integer or a decimal.) is the same shape as the graph for the original distribution approximates a normal curve
