Part A

1. Paste your completed "Frequency Table for Exam Scores" in Part A, #1. (5 points)
2. Paste your completed "Frequency Bar Chart for Exam Scores" in Part A, #2. (5 points)
3. Paste your completed "Relative Frequency Bar Chart for Exam Scores" in Part A, #3. (5 points)
4. The data for Part A has been displayed in four ways:

1. Raw Data for Exam Scores
2. Frequency Table for Exam Scores
3. Frequency Bar Chart for Exam Scores
4. Relative Frequency Bar Chart for Exam Scores

Provide an in-depth rationale of which data display that you personally find the most compelling and which the least compelling . This is subjective. There is no right or wrong response. (2 points)

Part B Car Fuel Consumption, Weight and Displacement

2. Is there positive or negative correlation between Highway Fuel Consumption and Weight? Briefly explain . (2 points)
3. Make some observations from the chart (2 points)
4. Interpret \({{R}^{2}}\) . (2 points) [Do not use R in your interpretation.]
5. What is the best predicted fuel consumption rate, to the nearest tenth, for a car that weighs 3000 lb? Hint: Substitute 3000 for y in the trendline equation and solve for x. You must show your work. (2 points)
6. Paste your completed chart in your Answer Form document in Part B, # 6 . (5 points)
