All these 3 scenarios will share the general NORMAL CURVE.
MEAN 0 and STD DEV 1 is the standard normal curve.
MEAN 5 and STD DEV 0.5 would be the curve is shifted 5 units to the right (relative to the standard normal) and the curve is more compressed (I'm unable to draw).
MEAN 100 and STD DEV 8 means the curve is shifted 100 units to the right (relative to the standard normal, i.e. centre of the curve is at 100) and the curve is more flat as compared to the previous 2 due to the wide standard deviation.
Hope this helps.
