k Drawing a Normal Probability Distribution Graph

You can draw a normal probability distribution graph using manual graphing with the

Run-Matrix mode.

1. From the Main Menu, enter the Run-Matrix mode.

2. Input the commands to draw a rectangular coordinate graph.

3. Input the probability value.

Example To draw a normal probability P (0.5) graph.

1 m Run-Matrix

!m(SET UP)2(Line)J

2 !4(SKETCH) 1(Cls) w

5(GRAPH) 1(Y=)

3 K6( g) 3(PROB) 6( g) 1(P() a.f)w

k Calculations Using the Distribution Function

You can use special functions in the Run-Matrix mode or Program mode to perform

calculations that are the same as the Statistics mode distribution function calculation (page

6-50).

Example To calculate normal probability distribution in the Run-Matrix mode for

the data {1, 2, 3}, when the population standard deviation is

= 1.5 and

the population mean is  = 2.

1. From the Main Menu, enter the Run-Matrix mode.

2. Press the keys as follows.

!m(SET UP)2(Line)J

K5(STAT) 3(DIST) 1(NORM)

1(Npd) !*( { ) b,c,d

!/( } ) ,b.f,c)w

“Performing Distribution Calculations in a Program” (page 8-42).
