One graph in the figure represents a normal distribution with mean mu = 12 and s

Question

One graph in the figure represents a normal distribution with mean mu = 12 and standard deviation sigma = 3. The other graph represents a normal distribution with mean mu = 16 and standard deviation sigma = 3. Determine which graph is which and explain how you know. Choose the correct answer below. A. Graph A has a mean of mu = 12 and graph B has a mean of mu = 16 because a larger mean shifts the graph to the right. B. Graph A has a mean of mu = 16 and graph B has a mean of mu = 12 because a larger mean shifts the graph to the right. C. Graph A has a mean of mu= 12 and graph B has a mean of mu = 16 because a larger mean shifts the graph to the left. D. Graph A has a mean of mu = 16 and graph B has a mean of mu = 12 because a larger mean shifts the graph to the left.

Explanation / Answer

from above as we can see that graph of B has been shifted on right due to larger mean.

therefore option A is correct.
