! Required information The article "Gypsum Effect on the Aggregate Size and Geometry of Three Sodic Soils Under Reclamation" (I. Lebron, D. Suarez, and T. Yoshida, Journal of the Soil Science Society of America, 2002:92-98) reports the effect of gypsum on the electric conductivity (in dS m¯¹) of soil. Two types of soil were each treated with three different amounts of gypsum, with two replicates for each soil-gypsum combination. The data are presented in the following table. Gypsum (g/kg) Soil Type Las Animas Madera 0 1.52 1.05 1.01 0.92 0.27 0.46 1.49 0.91 1.12 0.92 0.99 0.92 0.88 0.92 Is there convincing evidence of an interaction between the amount of gypsum and soil type? Compute the test statistic, find the P- value and state a conclusion. (Round the final answer to three decimal places.)
