Continuous, symmetrical, bell-shaped, with equal mean, median, mode.
68% of all values lie within ±1 standard deviation.
Find mean, then use: sqrt(sum((value - mean)^2)/n).
Mean (μ) = 13.5cm, as it's the median in normal distribution.
Calculate Z = (18-13.5)/1.5, then find P(Z > value).
95% of values lie within ±2 standard deviations.
Sketch the curve showing mean and 3 standard deviations.
It refers to the area to the right of the value on the curve.
It allows applying information from one side to the other.
Double-check arithmetic, especially in standard deviation steps.
