A2: Incomplete

Q2, part I: Displacement vs MPG is a negative association. Please verify the remaining associations are correct.
Q3: Please follow the instructions on which parameters should be included in the model and recalculate, to find the correct parameter coefficients and respective intercept value.
Q4. Recalculate after re-doing Q3

@KasraVakiloroayaei confirming corrections have been made.

Q2 p1: corrected Displacement answer and verified other responses

Q3: adjusted to add y_train and y_test

Good work with Q3, although recall that we are interested in numeric predictors only, thus float or integer types of data.

Also your Q4 had an error. please see below:

Thanks @KasraVakiloroayaei,

Q3 edited to select columns using select_dtypes on int and float instead of using names.

Q4 is now running correctly.
