One graph in the figure represents a normal distribution with mean mu = 15 and s

Question

One graph in the figure represents a normal distribution with mean mu = 15 and standard deviation sigma = 2. The other graph represents a normal distribution with mean mu = 7 and standard deviation sigma = 2. Determine which graph is which and explain how you know. A. Graph A has a mean of mu = 15 and graph B has a mean of mu = 7 because a larger mean shifts the graph to the right. B. Graph A has a mean of mu = 7 and graph B has a mean of mu = 15 because a larger mean shifts the graph to the left. C. Graph A has a mean of mu = 15 and graph B has a mean of mu = 7 because a larger mean shifts the graph to the left. D. Graph A has a mean of mu = 7 and graph B has a mean of mu = 15 because a larger mean shifts the graph to the right.
