Q2: An experiment of pyrolysis of biomass feed in a reactor was carried out and the weight of the biomass feed (\%) as a function of time (min) was recorded as below (Table 1): Table 1: Time evolution of the weight of the biomass feed. Answer the following questions: (a) Fit the experimental data into a linear regression model. [8 marks] (b) Calculate the coefficient of regression, r2, and assess the significance of the model. [8 marks ] (c) Find a 95% confidence interval for the slope of the regression line. [4 marks] (d) For the data given in Q2 (Table 1), develop a MATLAB code to validate all answers and plot the corresponding graph. Upload the MATLAB code with output window as a pdf file with your assignment. [12 marks] (e) Fit the data given in Q2 (Table 1) into a second order polynomial model and plot the graph. Upload the MATLAB code with output window as a pdf file with your assignment. Does it fit better than the linear model? [8 marks ]
