Belinda is a wedding planner who wants to help couples determine how many people to invite to their wedding. She collects data on hundreds of weddings and finds that you can predict the number of guests based on the total number of immediate family members (parents, siblings, children) of the couple. The equation for doing so is: (Guests)-hat = 38.28 + 15.47 (Family Members)
What is the best prediction for the number of guests a couple with a total of 12 family members? (Do not round your answer)
