9. The boiling temperature of water TB at various altitudes h is given in the following table. Determine a linear equation in the form TB=mh+b that best fits the data. Use the equation for calculating the boiling temperature at 17,000 ft. Make a plot of the points and the equation. ] After you have finished all the plotting cmds, the use the savefig and print cmds Use the polyfit cmd to fit the data to a 1st degree polynomial (straight line) Add the text Least Squares Approximation to the figure, with Fontsize 14 Use the linestyle 'ob' for hollow blue circles, i.e. plot (x,y,ob '); use grid on 10. Create a 22 tiledlayout with 4 plots and use the following xy data in each plot. Plot the fitted polynomials as described below and plot the data as points. (a) Fit the data with a degree 1 polynomial (b) Fit the data with a degree 2 polynomial (c) Fit the data with a degree 4 polynomial (d) Fit the data with a degree 8 polynomial Use the polyfit cmd to fit the data
