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. This problem must be supported by an UPLOAD as designated within part 1, under assessments>assignments>final exam work within 15 minutes of your test completion. Otherwise a 0 will be manually recorded for the points of this entire problem.

Railcars Units/mile 15 45 25 50 18 70 32 85 40 100 45 120 19316T 33 55 130 40 80 28 65 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 #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)
