Note that transmission type is not included in the nal model.
Do not use any packages that are not in R-base or the library datasets.

Was the report done in Rmd (knitr)?
On the other hand, mpg increases with respect to having a manual transmission (by.8).




This is very deja de ser tu joe dispenza pdf close to our original model with 2 more variables.Residual plots (see appendix) suggest that some transformation may be necessary to achieve linearity.The r2 for this model.866 which means that this model explains.6 of the variation in mpg.We used the model t by AIC which includes the variables cylinder, horsepower, weight, and transmission type.3 videos, 3 readings, 1 practice quiz.Reading: Lesson Learning Objectives, video: Outliers in Regression, video: Inference for Linear Regression.
