You can calculate normal probability distributions for single-variable statistics with the
RUN
•
MAT Mode.
Press K6(g)1(PROB) to display a function menu, which contains the following items.
•{P(}/{Q(}/{R(} ... obtains normal probability {P(t)}/{Q(t)}/{R(t)} value
•{t(} ... {obtains normalized variate t(x) value}
•Normal probability P(t), Q(t), and R(t), and normalized variate t(x) are calculated using
the following formulas.
P (t)Q (t)R (t)
Example The following table shows the results of measurements of the height
of 20 college students. Determine what percentage of the students fall
