Use mean and standard deviation to fit normal distributions and estimate population percentages with technology.
Interpret how changing the mean or standard deviation changes a normal model
Problem
How does a normal model change if the mean increases while the standard deviation stays the same?
Big Picture
What this problem is really about
Keep the two parameters in separate mental boxes: one controls where a normal curve is centered, while the other controls how spread out it is. Track only the parameter named as changing and treat the unchanged parameter as a constraint. That prevents a movement of the distribution from being mistaken for a change in its shape.
