Unformatted text preview: the scenario for the X variable and the Y variable. 4. Interpret the estimated slope coefficient in each situation. Use the data in problem 11.5 (page 450). You are not expected to test anything, just compute all the items listed below. For each plant, A, B, and C, calculate: 1. the sum of the observations ∑ X 2. the sum of the squared observations ∑ X 2 3. the mean for each plant (X bar) 4. the overall mean of the 15 observations (ignoring which plant it came from) 5. the sum of the squared deviations around the mean ∑ ( X minus X bar) 2 6. the numerator of the ratio under the radical in formula 4.12 (the two sum formula) in chapter 4 of your text...
