Question 2

Regression analysis is done on the variables Exam 1 and Exam 2 to determine if there is a linear relationship between the 1st and 2nd exam grades in a distance education course. From the statistical output below what is the conclusion at the level?
  The regression equation is
  Exam 2 = 33.9 + 0.595 Exam 1
   
  Predictor Coef SE Coef T P
  Constant 33.93 16.02 2.12 0.058
  Exam 1 0.5949 0.2111 2.82 0.017
   
  S = 13.7534 R-Sq = 41.9 R-Sq(adj) = 36.6
  1.There appears to be no statistical linear relationship between the exam grades.
  2.There appears to be a statistical linear relationship between the exam grades.
