BIOL 4500 Problem Set 10

BIOL 4500 Problem Set # 10 Name_________________________ You are interested in the effect of two treatments, a slow-release fertilizer and a fast- release fertilizer, on seed yield of peanut plants compared to a control of a standard fertilizer. When setting up the experiment, you recognize that some of the peanut plants were not at the same level of development or health. Consequently, you record the height (cm) of the plant, a measure of plant development and health, at the start of the experiment. Using the data below, answer the following problems. Control Slow-release Fast-release Yield(g) Height(cm) Yield(g) Height(cm) Yield(g) Height(cm) 87 68.3 134 72.2 150 76.3 77 64.3 122 69.2 143 72.2 69 60.0 137 75.1 121 70.4 80 66.7 110 64.0 101 64.8 120 72.3 97 62.5 109 67.0 111 71.8 155 70.0 111 68.5 67 61.0 149 71.1 145 71.0 68 66.7 148 74.3 161 74.1 99 72.4 142 67.7 133 69.1 91 68.3 132 66.2 139 70.9 84 64.8 135 66.8 120 66.6 77 66.7 128 64.8 115 65.0 121 74.9 92 63.4 89 61.9 122 72.5 151 75.2 94 62.5 109 65.7 144 69.8 142 71.0 75 62.0 103 64.2 137 68.2 79 64.8 117 71.2 158 74.0 103 66.0 129 67.2 160 77.2 123 70.2 95 60.9 123 69.0 90 63.0 151 69.5 135 68.7 1. What statistical test did you choose to use? Why? (2 pts.) - I used a Multivariate test with the multiple points of data. 2. What evidence do you have that you meet the assumptions of your chosen test? (Provide lots of detail and output here!) (6 pts.) It is the only test I could get to work, to be honest. But from all the other tests that we have learned about this was the only one that seemed to fit given the number of trials we have. 3 sections but both with 2 sets of data. 3. Was the overall model significant? (2 pts.) Levene's Test of Equality of Error Variances a
