Salmon farms in Atlantic Canada have a problem of sea lice that attack the fish. Three alternative pesticides have been developed to kill the lice and are being tested on three different farms. We want to select a single pesticide for use on all three farms since pesticide can be carried in the water from one farm to another. Four different sections of each farm are randomly selected and used to test the three pesticides (one per section) together with a no-treatment option in the fourth section for comparison. After the treatment, the number of salmon attacked by sea lice per cubic metre of water is recorded:

a) State the hypotheses.

b) Perform an ANOVA analysis with α = 0.05.

c) State the conclusions in business terms, including recommending the next step in the analysis.
