Question 4

a).

b).

One graph in the figure represents a normal distribution with mean = 6 and standard deviation o = 2. The other graph represents a normal distribution with mean = 13 and standard deviation o = 2. Determine which graph is which and explain how you know. A B Ma 6 13 Choose the correct answer below. A. Graph A has a mean of = 6 and graph B has a mean of = 13 because a larger mean shifts the graph to the left. B. Graph A has a mean of = 13 and graph B has a mean of = 6 because a larger mean shifts the graph to the right. C. Graph A has a mean of = 6 and graph B has a mean of = 13 because a larger mean shifts the graph to the right. D. Graph A has a mean of = 13 and graph B has a mean of = 6 because a larger mean shifts the graph to the left.
