Question

Compute the reisduals for the trend line shown. y = -0.5x + 5
​

Answer 1

X : 2__ 3 ___ 5 ___ 6 ___7

Y: 4 __3.5 __2.5___2 __ 1.5

Explanation:

Given tbe equation for tbe residual :

y = -0.5x + 5

X : 2, 3, 5, 6, 7

X = 2

Y = - 0.5(2) + 5 = 4

X = 3

Y = - 0.5(3) + 5= 3.5

X = 5

Y = - 0.5(5) + 5 = 2.5

X = 6

y = -0.5(6) + 5 = 2

X = 7

y = -0.5(7) + 5 = 1.5

X : 2__ 3 ___ 5 ___ 6 ___7

Y: 4 __3.5 __2.5___2 __ 1.5
