Answer:

predicted: 15.7

residual: 1.3

Step-by-step explanation:

In x-axis, age of the tree is represented, and in y-axis, height of the tree is represented. When the tree is 5 years, x = 5, and the predicted value is:

f(5) = 1.3(5) + 9.2 = 15.7

Residual value is computed as follows:

residual = observed - predicted

residual = 17 - 15.7 = 1.3
