k Normal Probability Distribution Calculation You can calculate normal probability distributions for single-variable statistics with the Run-Matrix mode. Press K6(g)3(PROB)6(g) 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. Standard Normal Distribution P (t) Q (t) R (t) 0t 0t 0t Example σx The following table shows the results of measurements of the height of 20 college students. Determine what percentage of the students fall in the range 160.5 cm to 175.5 cm. Also, in what percentile does the 175.5 cm tall student fall? Class no. Height (cm) Frequency 1 158.5 1 2 160.5 1 3 163.3 2 4 167.5 2 5 170.2 3 Class no. Height (cm) Frequency 6 173.3 4 7 175.5 2 8 178.6 2 9 180.4 2 10 186.7 1 6-27
