   Question

   The following descriptive statistics are available for two variables X and Y:

   

   Furthermore, we know that the correlation between X and Y equals r = +.87. What is the regression equation to predict Y from X?

   
   
   1. TRUE: Ŷ = 0.65X + 0.17
   2. FALSE: Ŷ = 1.17X + 0.68
   3. FALSE: Ŷ = 1.17X - 1.71
   4. FALSE: Ŷ = 0.65X + 1.98
