The amounts are in micrograms of arsenic and all samples have the same serving size. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Do the amounts of arsenic appear to be different in the different regions? Given that the amounts of arsenic in the samples from region A have the highest mean, can we conclude that brown rice from region A poses the greatest health problem? -Click the icon to view the data table of the arsenic amounts.
