$2.$ Consider a gas in a piston$-$cylinder device in which the temperature is held constant. As the volume of the device is changed, the pressure was measured. The volume and pressure values are reported in the following table.

Plot them on a graph as circles. Use the interactive fitting tool to fit the data to a first$-,$ second$-,$ third$-,$ and fourth$-$ order polynomial. Check for the goodness of fit. Display the equations and R$2$ values on the figure, and paste the figure below.
