One graph in the figure represents a normal distribution with mean = 15 and standard deviation o = 2. The other graph represents a normal distribution with mean u = 7 and standard deviation o = 2. Determine which graph is which and explain how you know .. Choose the correct answer below. OA. Graph A has a mean of μ = 15 and graph B has a mean of µ = 7 because a larger mean shifts the graph to the left. OB. Graph A has a mean of µ = 15 and graph B has a mean of μ = 7 because a larger mean shifts the graph to the right. OC. Graph A has a mean of u = 7 and graph B has a mean of μ = 15 because a larger mean shifts the graph to the right. G D. Graph A has a mean of μ = 7 and graph B has a mean of µ = 15 because a larger mean shifts the graph to the left. 7 15 B M
