Consider the weights from Exercise 4. The side-by-side boxplots below show little difference between the two groups. Should this be sufficient to draw a conclusion about the accuracy of the weigh-in-motion scale?

Data From Exercise 4

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.
