(GRAPH) Sketch a normal curve that has a mean of 15 and a standard deviation of 4. On the same x-axis, sketch another normal curve that has a mean of 25 and a standard deviation of 4. Describe the two normal curves.

That means the center of the x-axis on your normal curve has the number 15 (the mean of 15), then 1 z score to the left is the number 11, and one to the right of the 15 is 19. We know that 68% of all the data pieces lay within one standard deviation of the mean. Continue outward for three standard deviations. Along the x-axis begin a curve that has a mean of 25 (so you will see that the two normal curves are side by side on the cartesian plane).
