Question

For a sample of five students, the amount of time in hours each studied for an exam (x) and the score on the exam (y) were recorded. The results were x = hours studied 1 2 3 4 8 y = score on exam 70 75 68 98 99 NOTE: The equation of the least squares line is y = 65.726 + 4.52055 x . If a student studied 2.5 hours of the exam, what score does the least square line predict the student achieved? (Round your final answer to three decimal places, but do not round during intermediate steps.) Predicted score =
