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 Soll Science Society of America, $2002$:$92-98)$ reports the effect of gypsum on the electric conductivity $($in $d{S}^{-1})$ 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.

$\backslash$table$[[\backslash$table$[[$Gypsum$],[($g$/$kg$)]],$Soil Type$],[$Las Animas,Madera$],[0,1\mathrm{.}52,1\mathrm{.}05,1\mathrm{.}01,0\mathrm{.}92],[0\mathrm{.}27,1\mathrm{.}49,0\mathrm{.}91,1\mathrm{.}12,0\mathrm{.}92],[0\mathrm{.}46,0\mathrm{.}99,0\mathrm{.}92,0\mathrm{.}88,0\mathrm{.}92]]$

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.$)$

The test statistic is The $P-$value is

There

$]$ convincing evidence of an interaction between the amount of gypsum and soil type.
