Four new brands (A, B, C, and D) of fertilizer that a farmer can use to grow crops just came on the market. Before deciding which brand he should use permanently for all crops, a farmer decided to experiment for one season. To do so, he randomly assign each fertilizer to five one-acre tracts of land that he used to grow wheat. The following table gives the production of wheat (in bushels) for each acre for four brands of fertilizer Fertilizer A 73 70 71 65 76 71 16.5 Fertilizer B Fertilizer C Fertilizer D 75 82 82 80 86 81 16.0 68 80 87 86 84 78 83 15.0 76 73 71 73 13.5 Sample mean Sample variance Population mean (b) Write a statistical model for this experiment and state assumptions associated with the elements in the model. Estimate all of the parameters in the model (c) Find a 95% confidence interval for μC-1D. (d) Use the Fisher LSD method to make comparisons between the pairs of means. Use α = 0.05
