2. Select the distribution type you want to use for the probability value calculation.
• Here we want to select binomial distribution. Confirm that
“Binomial” is highlighted and then press w.
• This displays the binomial distribution parameter input
screen.
3. Specify the Tail setting.
• Confirm that Tail is highlighted, and then press one of the function keys from 1 to 4.
The following explains the meaning of each of the available settings.
1(
) ... Specifies data value x, and calculates cumulative probability within the range
equal to or less than
x.
2(
) ... Specifies the data value Lower boundary (Lower) and Upper boundary
(Upper), and calculates cumulative probability within that range.
3(
) ... Specifies data value x, and calculates cumulative probability within the range
equal to or greater than x.
4(
) ... Specifies data value x, and calculate probability for x.
• Here, we are calculating cumulative probability when
x ≤ 2, so we press 1( ).
4. Input values for the parameters.
• Use c to move the highlighting to the desired parameter, and then input a value.
(1) Highlight “
x”, input 2, and then press w.
(2) Highlight “Numtrial”, input 5, and then press w.
(3) Highlight “
p”, input 0.5, and then press w.
Note
• If you need detailed information about each parameter,
press the parameter input screen’s 6(DETAIL) key.
• The parameters whose values you need to input depend
on your Tail setting and selected distribution type. For
details, see the “Parameter List” (page 18-3).
5. To execute the calculation, use c to highlight “Execute” and then press 1(EXE).
• If you have input all of the required parameters, pressing w executes the calculation, no
matter which parameter is highlighted.
• This displays the graph screen, which shows the
calculation results and the graph.
• At this time, you can change the highlighted x value and re-calculate the cumulative
probability.
