By using MATLAB, Plot the histogram of porosity and permeability samples (separately). Check the data visually (using the histograms) if they are Gaussian. State your observations. You may need to do some sensitivities to find the right bin size. The sensitivities must be presented. Explain/state your methodology and demonstrate you know the details behind it. You do not need to explain the details of the calculations and processes within the MATLAB functions. Describe your logics and analyses. Present the results using proper graphs & plots. They should be properly labelled.
