Chapter 18, Problem 4E

Vehicle weights II The calibration test for a new weight-inmotion method of weighing trucks was introduced in Chapter 6, exercise 52. Is this method consistent with the traditional method of static weighing? Are the conditions for matched pairs inference satisfied? Weights are in 1000s of pounds.
