I'm working on a engineering test / quiz prep and need an explanation and answer to help me learn.
A simple linear regression model is estimated for shopping-trip generation during a shopping-trip peak hour. The model is:
Number of peak-hour vehicle-based shopping trips per household =
0.12+0.09(HH size) +0.011(annual HH income in $000s) -0.12 (retail employment in neighbourhood-in 100s)
A particular household has 6 members and an annual income of $50,000. They live in a neighbourhood with 450 retail employees. They move to a new home in a neighbourhood with 150 retail employees.
Calculate the predicted number of vehicle-based peak-hour shopping trips the household makes after the move
