Use the data to predict the exam grade for a student who studies 10 hours per week. what is the equation of the line of best fit?
Predict the exam grade for a student who studies 10 hours per week. How did you make your prediction?

Exam grade obtained by the student is 94.5

Step-by-step explanation:

By using regression line calculator,

Equation of the regression line → y = 2.725x + 67.25

Here x = Hours studied

y = Exam grades

If a student studied for 10 hours per week,

By placing x = 10 hours in the regression equation,

y = 2.725(10) + 67.25

  = 27.25 + 67.25

  = 94.5

Therefore, exam grade obtained by the student is 94.5
