Question 1: An origin-destination survey in 10 travel-analysis zones provided the following data relating to zonal residential densities (households/acre) and average daily trip productions per household. Calibrate and plot a model of the form Y=a+bX. Do you think the calibrated model is acceptable and why? (The use of Excel or a similar tool is suggested, but the manual calculation is acceptable).

Density X: 42    5    25 10 4 15 20 12 14 22

Trip rate Y: 1.5 4.0 2.1 2.6 4.8 2.0 2.5 3.3 1.9 2.0
