Homework Answers
(1) the equation of the regression line:
y y = a + b?x= ?1.102 + 1.996?x
Y=-1.102+1.996*(-2) =-5.094
Y=-1.102+1.996*(4)=6.882
(2)the equation of the regression line:
y y = a + b?x= 66.399 + 4.905?x
Y=66.399+4.905*4 =86.019
Y=66.399+4.905*6 =95.829
(3) r=0.9856
positive correlation between X and Y
0.9856
