An analyst is interested in the relationship between number of cats a person has (an independent variable), number of dogs a person has (an independent variable) and the number of friends the person has (the dependent variable). She regresses number of FRIENDS on number of CATS and number of DOGS. The equation for the best-fitting straight line is
FRIENDS = 10 − 2(CATS) + 1(DOGS)
A) A person had 4 cats and 2 dogs. What is that person's predicted number of friends?
B) What is the regression residual for a person with 0 cats, 0 dogs, and 0 friends?
