Question

Question 1: (25 pts) 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. Sample number Inoculated Un-inoculated 1 1.76 0.66 2 1.45 0.85 3 1.23 1.00 4 1.53 1.44 5 2.34 1.01 6 1.96 0.75 7 1.79 1.51 8 1.21 0.92 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?
