Q1 . Suppose we want to know whether or not a college training program is able to increase the maximum vertical jump (in inches) of college basketball players. The data "Jump data" on D2L recorded the maximum height (in inches) the 20 college basketball players can reach before and after the training program. Use the 0.05 significance level to test the claim that the average height of the jumps after the program is significantly higher than the average before the program. Step 1: State the null and alternative hypotheses in symbols. Step 2: What test should you use? Step 3: What are the test statistic and p-value? Step 4: What is your decision to the null hypothesis? What is the conclusion in the context?

Q2. A study sought to demonstrate that soy beans inoculated with nitrogen-fixing bacteria yield more and grow adequately without the use of expensive environmentally deleterious synthesized fertilizers. The initial hypothesis was that inoculated plants would outperform their uninoculated counterparts. There were 8 inoculated plants (I) and 8 uninoculated plants (U). The plant yield was measured by pod weight for each plant is given on D2L (Plants data). Use 0.05 significance level to test the claim that the mean pod weight for the inoculated plants is higher than the mean pod weight for the uninoculated plants. Step 1: State the null and alternative hypotheses in symbols. Step 2: What test should you use? Step 3: What are the test statistic and p-value? Step 4: What is your decision to the null hypothesis? What is the conclusion in the context?
