Use the following information for question #8-9. As a family is getting ready for a big Thanksgiving dinner, Scottie, a stats student, wonders if there is a linear relationship between how many different side dishes her family makes and the amount of dishes she has to wash after the dinner. She gathers some data from her friends' families and calculates the following least squares regression line: Y = 3.45 +4.15x where y = the number of dishes to wash and x = the number of side dishes made. If Scottie's family is planning on making 12 side dishes. How many extra dishes should Scottie expect to wash, on average, for each additional side dish her family makes?
