how to do these questions on MATLAB using data from this website https://coastwatch.glerl.noaa.gov/ftp/glsea/avgtemps/2017/glsea-temps2017_1024.dat

9. Calculate the winter average (days 1 to 79 and days 355 to 365) for all 6 lakes (one average per lake). Is the order from warmest to coldest the same as with the yearly average calculated in step #1? 10. Make a graph for winter days only (days 1 to 79 and days 355 to 365) with all 6 lakes on one graph Title your graph, label your axes and have a legend (use the same colors, line types and legend as the graph you made in step #6). 11. Assuming that you can swim comfortably in the lake if the temperature is above 20 degrees. Calculate the number of days in the year you can swim for each of the 6 lakes. Make pie charts of the percentages of total days of the year that you can swim in the lakes. Make one pie chart per lake and put all 6 on the same figure. Indicate each lake clearly next to the pie chart in the figure. 12. You know you can create equations to approximate experimental data. Can you deduce some fit between the days and the water temperatures? Can you create an equation that would approximate the results? If yes, what is the equation? Is it the same fit for all the lakes? If not can you provide the formulas (equations) for each of the 6 lakes? Try your best here using knowledge from class. 9.
