Answer:
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.
