• Specifying σ = 1 and µ = 0 specifies standard normal distribution.
After setting all the parameters, align the cursor with [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.
