The data below are the final exam scores of 10 randomly selected history students and the number of hours they slept the night before the exam. Find the least-squares regression line for the given data. What would be the predicted score for a history student who slept 7 hours the previous night? Is this a reasonable question? Round the least-squares regression line values to two decimal places, and round the predicted score to the nearest whole number Hours, x Scores, y 3 5 2 8 2 4 4 5 6 65 80 60 88 66 78 85 90 90 30 71 OA. y=5.04x+56.11; 91; Yes, it is reasonable. OB. y= -5.04x+56.11; 21: Yes, it is reasonable. OC. y=5.04x+56.11; 91: No, it is not reasonable. 7 hours is well outside the scope of the model.
