Estimate Car MPG

Predict MPG consumption of a car based on

1. Transmission Type
2. Weight
3. Quarter Miles per second

The prediction trained on mtcars dataset extracted from the 1974 Motor Trend US magazineperformance for 32 automobiles (197374 models), using linear regression.

The general formula:

## 
## Call:
## lm(formula = mpg ~ factor(am) + wt + qsec, data = mtcars)
## 
## Coefficients:
## (Intercept)  factor(am)1           wt         qsec  
##       9.618        2.936       -3.917        1.226

• Automatic transmission: MPG = 9.62 - 3.92 * Weight + 1.22 * Quarter miles time
• Manual transmission: MPG = 12.56 - 3.92 * Weight + 1.22 * Quarter miles time
• The model predict an actual MPG with a variation of + or 4.9 MPG from the predicted MPG.
• Units of measure: Weight in 1000 lbs, Quarter Mile time in seconds.
