Find the residual if you know the actual number is 3 and the predicted value is 1.6 a. 1.4 b. 2.2 c. 0.4 d. there is no correct answer given e. -0.5

The correct option is A.

Step-by-step explanation:

The difference between actual value and predicted value is called residual.

Formula of residual is

Where, y is observed value or actual value and is predicted value.

The value of residual is 1.4 and option A is correct.

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
