The environmental department of the Maule region is analyzing various wetlands distributed in the coastal zone of the region, for which they have concentrated on measuring 17 wetlands at a certain time of year. The variables measured have been:

X1: Electrical conductivity, X2: Bicarbonate content, X3: Chloride content, X4: Sulfate content, X5: Calcium content, X6: Magnesium content, X7: Sodium content, X8: Potassium content, X9: Content in phosphates

It is requested that, using the available tables, you interpret the most important data and indicate your recommendations.
