What are the hypotheses to test? H0: mu 1 equals mu 2 equals mu 3μ1=μ2=μ3 H1: At least one of the population means is different from the others.At least one of the population means is different from the others. Determine the value of the test statistic. The test statistic is nothing.
Available below are amounts of arsenic in samples of brown rice from three different regions. 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
view the data table of the arsenic amounts.
