The predicting equation for the average live weight of the ewes using the proportion of land closed for the lambs before weaning is Y=23.496 +0.103X3. Which of the following is (are) TRUE? 1. The expected average live weight of the ewes when no area is closed for the lambs is 23.496 kg. II. The average live weight of the ewes is expected to decrease by 0.103 kg for every unit increase in the proportion of land closed for the lambs before weaning.

Question

A survey on lamb farms was conducted and data were collected on the following
variables from a random sample of 30 farmers.

Y = average live weight of ewes (kg)
X1 = area of grazing land (m2)

X2 = proportion of farm area that cannot be cultivated
X3 = proportion of area closed for lambs before weaning

 

The predicting equation for the average live weight of the ewes using the proportion of land closed for
the lambs before weaning is Y=23.496+0.103X3. Which of the following is (are) TRUE?
1. The expected average live weight of the ewes when no area is closed for the lambs is 23.496 kg.
II. The average live weight of the ewes is expected to decrease by 0.103 kg for every unit increase in
the proportion of land closed for the lambs before weaning.
