1. Select T > [Draw Function].
2. On the menu that appears, highlight the function you want to graph and then press O.
To find the y -values for x -values on a regression graph (Graph Solve)
While a regression graph is displayed, you can use the operation below to find the y -value for any x -value on
the graph.
1. Select T > [Graph Solve] > [y-Cal].
2. Use the dialog that appears to input the x -value and then press O.
• The x - and y -coordinate values on the regression graph are displayed at the bottom of the window.
• If both the x - and y -coordinate values are within the window's range, a pointer appears at the coordinates
on the graph.
• To redisplay the dialog and input another x -value, press O.
3. To exit this operation, press b.
To adjust the background image (Fade I/O)
You can use this operation to adjust the opacity of the background image. See

Drawing Graphs Using Multiple Graph Setups
Graph1, Graph2, and Graph3 in the Draw Statistics Graph menu are independent areas for configuring graph
settings. By default, None (Do not graph) is specified for Graph2 and Graph3, and only the Graph1 settings
are used for graphing.
If you want, you can use two or three graph setups to simultaneously draw multiple graphs.
Note the points below when using multiple graph setups for graphing.
• Pressing > to go from the Graph tab to the Results tab displays a menu for selecting a graph setup. Choose
a graph setup from the menu and press O.
• Graph setups for a 1-Variable graph in one area and a 2-Variable graph in another area cannot be used to
draw simultaneous graphs.
• When drawing a Pie Chart or Bar Graph, only the graph setup for the graph you are drawing should be
assigned to an area. None should be specified for the other areas. In the case of a Pie Chart or Bar Graph,
you can draw using only one graph setup at a time.
Performing a Hypothesis Test
Statistical hypotheses are tested in a variety of ways and results are presented numerically and graphically.
