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 64 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. *P(x) 0.04- 0-12.4 iP=19.4 (a) P(X) 0.04- 0-12.4 (b) AP(x) 0.35 0- = 1.55 =19.4 (c) AP(x) 0.04- -=12.4 19.4 0 G 0- G 50 -40 40 0 50 Time (in sec.)
