(c) (b) (a) approximates a normal curve is the same shape as the graph for the original distribution 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. (a) (b) (c) Graph most closely resembles the sampling distribution of the sample means, because ${?}_{\stackrel{?}{x}}=,{?}_{\stackrel{?}{X}}=$ and the graph (Iype an integer or a decimal.)
