How do I send the Excel data?

A driver reads your answer to part (4) and makes the following comment:

MapQuest gives driving times for cars. Driving times for trucks will probably

be longer because we can't go as fast, especially in city traffic. Is there some

way to adjust the MapQuest prediction to make it fit trucks better?

Construct a fitted line plot (scatterplot with fitted linear regression line) using the MapQuest

times as the predictor variable and the actual times as the response variable. Call the fitted

values 'Adjusted MapQuest' times. Provide the fitted line plot, regression equation and R2

values associated with the 'Adjusted MapQuest' times. Interpret your results and indicate

whether the driver's suggestion is valid or invalid.
