Question

p value, t- test, conclusion

The accompanying table gives amounts of arsenic in samples of brown rice from three different states. The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. 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 states? Given that the amounts of arsenic in the samples from Texas have the highest mean, can we conclude that brown rice from Texas poses the greatest health problem? E Click the icon to view the data. What are the hypotheses for this test? O A. Ho: H1 = H2 = H3 H,: At least one of the means is different from the others O B. Ho: H1 = H2 =H3 H1: 41 # H2 # H3 O C. H,: At least one of the means is different from the others H1: H1 = H2 = H3 O D. Ho: H1 # H2 * H3 H1: 41= H2 = H3
