Student Learning Outcomes . Calculate and construct the line of best fit between two variables. Evaluate the relationship between two variables. Collect the Data 1. 19 new vehicles were randomly selected. Their weight in pounds and fuel efficiency in miles per gallon were recorded in the following table: Weight (lbs) Fuel Efficiency (mpg) 2620 21.0 21.0 22.8 21.4 18.7 18.1 14.3 24.4 2875 2320 3215 3440 3460 3570 3190 3150 3440 3440 4070 3730 3780 5250 5424 5345 2200 1615 Table 12.11 22.8 19.2 17.8 16.4 17.3 15.2 10.4 10.4 14.7 32.4 33.9 2. Which variable should be the dependent variable, and which should be the independent variable? Why? 3. Construct a scatterplot of weight versus fuel efficiency. Plot the points.
