Observe the effect of mean and standard deviation on the shape and position of the distribution. What changes? What doesn't?

1. How do changes in mean affect the shape and position of the distribution? 2. How do changes in standard deviation affect the shape and position of the distribution? 3. Explain why the total area under the curve doesn't change. 4. What is the significance of the fact that the area shaded red remains constant?
