Transcribed Image Text:2. The following equations were established for a study area.
T=40+ 489x, -0.004x,-02-0.017.
(1₂=5₁4₂=3,1₂=9.44 = 1.2, R² = 0.69)
(r = 25, R² = 0.45)
where
T = 30 + 5.9X₁
T = 300 +0.25X₂
T = 25 +2.4X₁ + 0.15X₂
(t = 41, R² = 0.23)
X, = family income ($1000)
(4= 35,4 = 95, R² = 0.85)
T= trips/household
X₁ = vehicle ownership (cars/household)
X₂ = population density (persons/acre)
= distance from the CBD (miles)
175 be
The number of observations used in setting up these equations is 53. (R² and 1-tests results
