Instructions:
 Clickanddrag 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?
