P(t): Probability below a
given point x
P(t)=
Q(t): Probability below a
given point x and above
the mean
Q ( t ) = 0.5 – R ( t ),
R(t): Probability above a
given point x
R ( t ) = 1 – P ( t ),
Example: Calculate the probability distribution P(t) for the sample
data: 20, 43, 26, 46, 20, 43, when x = 26. ......
