Chemical Oxygen Demand (COD) is a necessary water fine parameter due to the fact similar to BOD, it affords an index to examine the effect discharged wastewater will have on the receiving environment. Table reduction of COD in wastewater by three different treatment methods. Test the hypothesis that the reduction percentage is no different for each treatment method. Use the 5% level of significance. 4 shows the means for the removal
