9 The Gas Mileage Of An Automobile As Follows Suppose That This Relationship As Shown By The Following Data On Speed 2 (15.19 KiB) Viewed 146 times
9. The gas mileage of an automobile as follows. Suppose that this relationship as shown by the following data on speed (mph) and mileage (mpg): Show work in the table below. MPG Speed 20 24 30 30 40 34 50 32 60 32 Find the following statistics Mean Speed: Mean MPG: Standard deviation of Speed: Standard deviation of MPG: Correlation: Fit the Least-squares Regression line Equation to predict MPG: Predict MPG at speed 30 and find residual: What percent of variation in MPG is explained by the Speed
Draw scatterplot for the data and sketch the least squares line. Label the variables properly. 10. Use data in the above question. Write the least squares regression line equation to predict Speed.
