An experiment was conducted to determine the effect of 2 different pesticides on the yield of fruit from 2 different varieties of a citrus tree. 20 trees from each variety were randomly selected from the orchard. The 2 pesticides were than randomly assigned to 10 trees of each variety. Then months later, when the trees bore fruit,the following observations were observed.

Calculating Marginal An experiment was conducted to determine the effect of 2 different pesticides on the yield of fruit from 2 different varieties of a citrus tree. Twenty trees from each variety were randomly selected from the orchard. The two pesticides were than randomly assigned to ten trees of each variety. Then months later. when the trees bore fruit. the following observations were observed. Pesticide Variety Mean 1.00 57.70 1. First, calculate the marginal means in table I.I then answer the questions 2.00 51 40 Table 1.1 Pesticide Pesticide A 1.00 14.30 Varieties 1 Pesticide B Marginal Mean 2.00 46.60 Marginal Mean 2. Using the Means on the Y axis and Pesticide on the X axis. Plot a simple line graph. There should be 2 different lines in the graph, one for each variety of plant. Does this graph indicate an interaction between the pesticides and variety of tree? If so how can you tell? Which Pesticide would you recommend and why? Which Variety would you recommend and why? Which final combination between the pesticides and variety yield the best results
