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 equation of the 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 regression line values to the nearest hundredth, and round the predicted score to the nearest whole number.

= 5.04x + 56.11; 91; No, it is not reasonable. 7 hours is well outside the scope of the model.
= 5.04x + 56.11; 91; Yes, it is reasonable.
= -5.04x + 56.11; 21; Yes, it is reasonable.
= -5.04x + 56.11; 21; No, it is  not reasonable. 7 hours is well outside the scope of the model.
