Instructions:
- Click-and-drag the left and right
end of the interval
we need to calculate the area under the genaral
normal curve.
- Change the values of the mean and standard
deviation.
Questions:
- Do the probabilities (areas under the curve) change
as the mean and the variance/SD
vary? Should they change? Why?
- Do the shape, spread, center of the curve change? Why?
- Do we get the same values as the ones from standard
Normal tables?
