Graph a relative frequency polygon. Before plotting the points, round the "Relative Frequency" values to 3 decimal places. Click the Plotter tool and drag the first point you want to plot onto the grid. Continue clicking and dragging the plotter tool until you have identified all of the necessary points for this line. To earn full credit for this graph, you must plot all required points for polygon. Once all points have been plotted, click on the line (not individual points) and a tool icon will pop up. You can use this to enter exact co-ordinates for your points as needed. Print References Polygon Relative Frequency 05 0.4 0.3 Relative Frequency 0.2 Mc
