Question 227766: The regression equation:
Y^ = 5 + 1.2X
was calculated from a sample. It is part of a regression model that has been developed in order to predict the score in an end-of-year exam based on the score in a mid-year exam for a particular university course. In the sample, mid-year scores ranged from 50 to 80.
Select whether or not each of the following conclusions are correct from the regression analysis:
Correct OR Not correct
a) For an increase by one in the mid-year score, the predicted increase in end-of-year score is 1.2.

b) If a student achieves a score of 45 in the mid-year exam then they will achieve a score of 59 in the end-of-year exam.

c) If a student achieves a score of 60 in the mid-year exam then they will achieve a score of 77 in the end-of-year exam.
