- Input the values of the random variable into L1 (remember to use the class midpoints for continuous random variables).
- Input the associated percentages, formatted as decimals, into L2.
- Press 2nd Y= and ENTER to edit stat plot 1.
- Press ENTER when the word ON is highlighted to turn on the stat plot.
- Select the histogram graphic and press ENTER.
- Set the Xlist: to L1.
- Set the Freq: to L2.
- Press WINDOW.
- Set up the window as follows:
- Xmin: lowest x-value from L1
- Xmax: a little higher than the highest x-value from L1
- Xscl: the “increment of change” of the x-variable in L1
- Ymin: 0
- Ymax: a little higher than the maximum probability from L2
- Yscl: Could use a lot of things here, but 0.05 works pretty well
- Xres: 1
- Press GRAPH. The calculator should now display the graph of the specified binomial distribution.
