A. Y=50, so Y^=50 B. X=50, so Y^=0.83+0.44(50)=22.83 C. X=50, so Y^=0.44+0.83(50)=41.94 D. Unable to find. 1a. If a student spennt 120 hours studying for this course, would you feeel comfortable to use your estimated regresssion equation to predict his points? Why? A. The range of X in our data is from 10 to 85. X = 120 is outside the range of X. I do not feel comfortable to use my estimated regression equation to predict his points as the linear relationship may not hold when X = 120. B. I know that 120 hours is…
