Question

One graph in the figure represents a normal distribution with mean mu = 9 and standard deviation sigma = 1. The other graph represents a normal distribution with mean mu = 13 and standard deviation sigma = 1 Determine which graph is which and explain how you know. Choose the correct answer below A Graph A has a mean of mu = 13 and graph B has a moan of mu = 9 because a larger mean shifts the graph to the left B. Graph A has a mean of mu = 9 and graph B has a moan of mu = 13 because a larger mean shifts the graph to the right C. Graph A has a mean of mu = 9 and graph B has a mean of mu = 13 because a larger moan shifts the graph to the left D. Graph A has a mean of mu = 13 and graph B has a mean of mu = 9 because a larger mean shifts the graph to the light.

Explanation / Answer

option (B) is correct and self explanatory. The red curve has mid point of 9 and blue curve has mid point of 13, so clearly curve A has mean 9 and curve B has mean 13.
