Answer:
Residual for the week will be $6.
Step-by-step explanation:
Regression equation predicting the per barrel cost of jet fuel is,

where,
= cost of jet fuel
x = cost of crude oil per week
If the cost of crude oil in any week = $60
Then predicted cost of jet fuel,
![\hat{y}=2+[\frac{7}{6}\times (60)]](https://tex.z-dn.net/?f=%5Chat%7By%7D%3D2%2B%5B%5Cfrac%7B7%7D%7B6%7D%5Ctimes%20%2860%29%5D)
= 2 + 70
= $72
Residual price = Actual cost - predicted cost
= $78 - $72
= $6
Therefore, residual price will be $6.
