Question

The scatter plot shows the distance a car drives and the time it takes to get to the destination for many trips. Priya looks at the residuals for the travel time. For a trip that is 40 miles, is the actual travel time above or below the expected travel time? Explain your reasoning.

Answer 1

Priya can determine whether the actual travel time is above or below the expected travel time by examining the residuals for the trip that is 40 miles.

Step-by-step explanation:

The student wants to determine whether the actual travel time is above or below the expected travel time for a trip that is 40 miles. To do this, Priya looks at the residuals for the travel time. Residuals represent the difference between the actual value and the predicted value. If the actual travel time is above the expected travel time, the residual will be positive. If the actual travel time is below the expected travel time, the residual will be negative. Therefore, by examining the residual for the trip that is 40 miles, Priya can determine whether the actual travel time is above or below the expected travel time.
