Variables and tests Table 1.What is the question that Pickens is investigating? (Hint: Identify the variables he measures - e.g. what about the soil is he actually measuring?) (0.5 point) 2.Based on the data set (see Table 3-4) what is the dependent and independent variable? Consult variables and tests tableabove and identify the appropriate statistical test for this data set. Explain why the test you identified is appropriate for this data set. (1.5 points) 3.Based on farmer Pickens’ question, write a (statistical) hypothesis in terms of the dependent and independent variables. (1 point) Lab Activity 2 | Analysis of Corn Yield Data (5 points)We are interested in the effect of fertilization on corn yields. Corn plants were planted in two adjacentfields of the same size with similar soil, and receiving similar amounts of sunshine. During the growingseason, both fields were subjected to the same watering regime, but only one of the fields was fertilized. At the time of harvest, the corn yield of 100 randomly selected plants from each field was measured and compared. Download the corn yield data from canvas, and examine the data: focus on the number of categories and the data type. Consult Table 3-2 (on page 3-4) and identify the appropriate statistical test for this data set.
