The Great Plains Railroad is interested in studying how fuel consumption is related to the number of railcars for its trains on a certain route between Oklahoma City and Omaha. A random sample of 10 trains on this route has yielded the data in the table below. Railcars Units/mile 20 45 22 50 18 80 30 70 110 45 97 37 78 50 120 85 21 58 Blank #1: Sketch a scatter plot as part of your written work upload and then here in blank #1, describe the relationship you see. Is it linear or non-linear? Is it positive or negative? Is it weak or strong? Give your answer as a list of 3 items to answer these 3 questions, separated by a comma and no extra spaces. For example, a valid answer might look like linear,negative,weak. Blank #2: Report the correlation coefficient r to two decimal places. Blank #3: Write the equation of the regression line, rounding coefficients to two decimal places. Make sure your answer is in equation form, using the variables x and y as appropriate with no extra spaces or parentheses. (You will need your equation in the next problem)
