3. The measured soil water content of 16 samples at four depths is as follows: Soil Water contents ( cm³ / cm³) 0.31 0.29 0.34 0.28 0.31 0.31 0.29 0.07 0.28 0.28 0.28 0.15 0.25 0.25 0.24 0.08 a) At the 10% level of significance, Test if the means for the four depths differ? b) Check the assumption of the model, and use the appropriate model.
