Question
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 225 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) (c) (b) = 12.9 SE AP(x) 0.04- 0 o = 12.9 iμ=X7.5 X 50 Time (in sec.) AP (X) -40 0.04- LA = 1.2 40 Time (in sec.) 0.04- -20 P(X) x = 12.9 = 17.5 X 50 Time (in sec.) Graph most closely resembles the sampling distribution of the sample means, because (Type an integer or a decimal.) μx = = AP (X) 0.55- o- = 0.86 x = 17.5 0 50 Time (in sec.) and the graph + is the same shape as the graph for the original distribution approximates a normal curve
