Ddw Welght (100 Ibs) For this data set, Xrepresents the weight of each car in hundreds of pounds; predicted fuel efficiency of each car in miles per gallon and Y represents the (mpg) A reasonable value for the slope of the regression line is -1.11. Which of the following statements is the most complete valid conclusion about the relationship between weight and fuel efficiency? Heavier cars tend to have lower mpg ratings: weight; we expect to see 1.11 mpg increase in For every 100-pound increase in car fuel efficiency: expect to see 1,11 mpg decrease in For every pound increase in car weight; we fuel efficiency: wC expect t0 see 1.11 mpg decrease in For every 100-pound increase in car weight; fuel efficiency
