Direction: Answer the following questions

Provide the appropriate descriptive statistics for the given: 1. A study was conducted to demonstrate that soy beans inoculated with nitrogen-aring bacteria yield more and grow adequately without expensive environmentally deleterious synthesized fertilizers. The trial was conducted under controlled conditions with turil'orm amounts of soil. The initial hypothesis was that inoculated plants would outperform their uninoculated counterparts. This assumption is based on the facts that plants need nitrogen to manufacture vital proteins and amino acids and that nitrogen-fitting bacteria would make more of this substance available to plants. increasing their size and yield. There were 3 inoculated plants {1! and E uninoculated plants [U]. The plant yield as measured by pod weight For each plant is given in Table 2. a. [is poms] Compute appropriate descriptive statistics for l and U plants. b. [to pitiful] Use a graphic method to compare the two groups. Table 2. Pod weight {d from inoculated [I] and uninoculated [U] plants I. Provide complete solutions then box your answers in solving the following: 1.
