Data on x= the weight of a pickup truck and y= distance required for a truck to stop traveling 40 miles per hour to come to a complete stop for 30 trucks was used to fit the least squares regression line, y = 26 + 0.05x. Which of the following statements is a correct interpretation of the value 26 in the equation of the least squares regression line?
a. on average, the stopping distance increases by 26 feet for each 1-pound increase in truck weight.
b. on average, the truck weight increases by 26 pounds for each additional foot in stopping distance.
c. on average, the stopping distance is 26 feet when the truck is at 0.
e. it is not reasonable to interpret the intercept in this setting because a weight of 0 is outside the range of the data used to fit the regression line.
Answer: E
