Calculate the residual for a student with an observed BMI of 25 and an observed hrs/month under the influence of 18.8. (Round your answer to two decimal places.)

a. 6.20

b. - 1.65

c. 1.65

d. 4.55

Option A.

Step-by-step explanation:

We need to find the residual for a student with an observed BMI of 25 and an observed hrs/month under the influence of 18.8.

Actual value = 25

Predicted value = 18.8

Residual = Actual value - Predicted value

Residual = 25 - 18.8

Residual = 6.2

Round the answer to two decimal places.

Residual = 6.20

The residual value is 6.20.

Therefore, the correct option is A.
