A department of transportation would like to measure the weights of commercial trucks on its highways without the expense of maintaining weigh stations along the highway. Weigh stations aggravate truckers, are expensive to operate, and delay shipments. To see if a proposed remote weigh system was accurate, transportation officials conducted a test. They weighed trucks when stopped on a regular scale. They then used the remote system to estimate the weights. The data is shown to the right.
