8) Use the Energy&Meteorology file for this part. The file has different columns (Air Temperature (F), relative Humidity(%), Pressure (10^5 Pa), shortwave radiation (Wm^(-2)), wind speed (m/s) and Energy use (GWh)) and consists 13 days of data from San Juan Puerto Rico. Find the relationship between energy use and the different variables using simple statistical tools like linear regression and find the best match. Plot your results and discuss the findings in no more than 250 words.
