2 Question 2 Data on the vapor pressure P of water as a function of temperature T are given in the following table. Determine whether the data can be described best by a second order polynomial (y ax+bx+c) fit or by an exponential fit (y= bema) by calculating the MAPE(Mean Absolute Percentage Error). Develop a model of the pressure as a function of temperature using the polyfit command, and use best fit curve to estimate the pressure at a temperature of T = 300 K.
