Answer
The APLS formula overestimate the weight of the children under 1 year of age the because
the actual weight line lies below the APLS UK line.It means every time we predict weight of
the children,we get the weight which is higher than the actual weight.

Answer
The novel formula is
Weight =3.161+0.502*age in months

Substituting age = 9 months
Weight =3.161+0.502*9 = 7.68 kg.

Answer
Predicted equation is
Weight = 3.161+0.502*Months
Weight =3.161+0.502*2 = 4.17 kg

Answer
Given equation
Weight =0.176*Age in months+7.241
Y-intercept when age =0 which is 7.241
Slope = 0.176

Answer
Weight =7.241+0.176*age
Substitute age =3 years =12*3 =36 month
Weight =7.241+0.176*36 = 13.58 kg

Answer
Predicted equation,Weight = 7.241+0.176*age
Substitute age =5 year=60 months
Weight =7.241+0.176*60 = 17.8 kg

Answer
The actual weight line is above the predicted line upto 8 years of age of children, thereafter
the actual line is below the predicted line. The predicted line is calculated based on the least

sum of square of the residual(observed-predicted).It is very much expected as th...
