A new microwave assisted extraction method for the recovery of 2-chlorophenol from soil samples was evaluated by applying it to five different soils on each of three days. The percentage recoveries obtained were: Soil 1 2 3 4 5 1 67 78 78 70 69 Day 2 69 66 73 69 71 3 82 76 75 87 80 Determine whether there were any significant differences in percentage recovery (a) between soils, and (b) between days
