Find the coofficiant of determination 6. An engineer wanted to determine how the weight of a car affects gas mileage. The following data represent the weights of various cars and their gas mileages, Complete parts (a) through (d). Car Car weight (pounds) Miles per Gallon A 3500 19 B 3800 18 C 3000 24 3200 23 3000 22 a) Which variable is likely the explanatory variable and which is the response variable? explanatory variable response variable b) Draw a scatter diagram of the data. C) Determine the linear correlation coefficient between car weight and MPG. Note: Write formula and answer with 2 decimal places d) Does a linear relation exist between the car weight and MPG Write a good conclusion. e) Find the regression equation f ) Predict the car MPG when weight is 3000 lbs. g) Find the residual for x = 3000 h ) Find the coefficient of determination
