6-7-3 Distribution k Normal Distribution u Normal Probability Density Normal probability density calculates the probability density of nomal distribution from a specified x value. Normal probability density is applied to standard normal distribution. f(x) = 1 2πσ (x - µµ)2 - e 2σ 2 (σ > 0) Perform the following key operations from the statistical data list. 5(DIST) 1(NORM) 1(Npd) Data is specified using parameter specification. The following shows the meaning of each item. x data standard deviation (σ > 0 mean Save Res list for storage of calculation results (None or List 1 to 26) Execute executes a calculation or draws a graph • Specifying σ = 1 and µ = 0 specifies standard normal distribution. After setting all the parameters, use c to move the highlighting to "Execute" and then press one of the function keys shown below to perform the calculation or draw the graph. • 1(CALC) ... Performs the calculation. • 6(DRAW) ... Draws the graph.
