Priva takes not of the distance the car drives and the time it takes to get to the destination for many trips.
Use technology to create a scatter plot of the data, add a line of best fit to the graph, and find the correlation coefficient.
• Distance is one factor that influences the travel time in
Priya's car trips. What are some other actors?
• Which of these factors (including distance) most likely has the most consistent influence for all the car trips?
Explain your reasoning.
• What do the slope and y-intercept for the line of best fi mean in this situation?
• Based on the correlation coefficient, how would you describe the strength of the linear relationship?
• How long do you think it would take Priya to make a trip of 90 miles if the linear relationship continues? If she drives 90 miles, do you think the prediction you made will be close to the actual value? Explain your reasoning.
