The purpose of this study was to demonstrate that soy beans inoculated with nitrogen$-$fixing bacteria yield more and grow adequately without expensive environmentally deleterious synthesized fertilizers. There were $8$ inoculated plants and $8$ un$-$inoculated plants. The plant yield as measured by pod weight $($in grams$)$ for each plant is given in the table below.

$\backslash$table$[[$Sample number,Inoculated,Un$-$inoculated$],[1,1\mathrm{.}76,0\mathrm{.}66],[2,1\mathrm{.}45,0\mathrm{.}85],[3,1\mathrm{.}23,1\mathrm{.}00],[4,1\mathrm{.}53,1\mathrm{.}44],[5,2\mathrm{.}34,1\mathrm{.}01],[6,1\mathrm{.}96,0\mathrm{.}75],[7,1\mathrm{.}79,1\mathrm{.}51],[8,1\mathrm{.}21,0\mathrm{.}92]]$

The initial hypothesis was that inoculated plants would outperform their un$-$inoculated counterparts. What is your overall impression concerning the pod weight in the two groups?
