Consider the data Repair. (a) Develop the estimated simple linear regression equation to predict the repair time (y) given the type of repair (x1). x1 = 0 if the type of repair is mechanical and 1 if the repair is electrical. (c) Develop the estimated linear regression equation to predict the repair time (y) given the type of repair (x1) and the repairperson who performed the service (x2). x1 = 0 if the type of repair is mechanical and 1 if the repair is electrical. X2 = 0 if Bob Jones performed the service and 1 if Dave Newton performed the service. Between (a) and (c), which one is a better fit? Why?
