The vertical distance between a senior student with a height of 160 cm and his estimated height of 157.06 cm is 2.94 cm
Explanation:
Given data,
Term Co eff
Constant 105.08
Foot length 2.599
Solving the problem for the given data
Frame the equation,
X= constant+ foot length ( foot length of 20 cm)
X=105.08+2.55(a)
Where X denotes the predicated height
a denotes the foot length 20 cm
X=105.08+2.55(20)
X=157.06
The residual computed is given as
Z denotes the residual component
Z=Y-X
Z=160-157.06
Z=2.94 cm
Interpretation:
The vertical distance between a senior student with a height of 160 cm and his estimated height of 157.06 cm is 2.94 cm
