Jason recently performed an experiment with his car using different types of gasoline to see if he can improve his gas mileage. He has compiled his data and he needs someone to create a graph for him. This is your assignment. Please create a graph makes a difference. Graph the data and determine if using a different grade of gasoline give your graph Variable on the $x$ axis. Item being tested and the results in miles per gallon (MPG): \begin{tabular}{ll} Type of Gas & Result \\ 88 Octane Gasoline & 26 \\ 89 Octane Gasoline & 28 \\ 90 Octane Gasoline & 30 \\ 91 Octane Gasoline & 27 \end{tabular}

Solution

Solution Steps

Step 1: Identify Variables

The independent variable (x-axis) is the octane rating of the gasoline. The dependent variable (y-axis) is the resulting miles per gallon (MPG).

Step 2: Plot the Data Points

87 Octane: 26 MPG (This is Jason's normal usage and is not part of the experiment table but included in the text)
88 Octane: 26 MPG
89 Octane: 28 MPG
90 Octane: 30 MPG
91 Octane: 27 MPG

Step 3: Analyze the Graph

The graph shows that gas mileage increases from 87 octane to 90 octane but decreases at 91 octane. The greatest mileage achieved is 30 mpg with 90 octane gasoline. Thus, using a higher octane gasoline does appear to make a difference, at least up to a point.

Final Answer

The provided image attempts to graph the data. However, it lacks clear labels and accurate plotting of the points. A proper graph would clearly show the octane rating on the x-axis, MPG on the y-axis, and accurately plotted data points for each octane level and its corresponding MPG. Based on the data, a different grade of gasoline does appear to impact MPG.
