The exercice is validated is all questions of the exercice are validated

The question 1 is validated if the output of y_train.values[:10] and y_test.values[:10]are:

```console
y_train.values[:10]: 
[[202.]
[ 55.]
[202.]
[ 42.]
[214.]
[173.]
[118.]
[ 90.]
[129.]
[151.]]

y_test.values[:10]: 
[[ 71.]
[ 72.]
[235.]
[277.]
[109.]
[ 61.]
[109.]
[ 78.]
[ 66.]
[192.]]
```

The question 2 is validated if the coefficients and the intercept are:

```console
[('age', -60.40163046086952),
('sex', -226.08740652083418),
('bmi', 529.383623302316),
('bp', 259.96307686274605),
('s1', -859.121931974365),
('s2', 504.70960058378813),
('s3', 157.42034928335502),
('s4', 226.29533600601638),
('s5', 840.7938070846119),
('s6', 34.712225788519554),
('intercept', 152.05314895029233)]
```

The question 3 is validated if the output of predictions_on_test[:10] is:

```console
array([[111.74351759],
    [ 98.41335251],
    [168.36373195],
    [255.05882934],

    [126.28961941],
    [117.73121787],
    [224.83346984]])
```

The question 4 is validated if the mse on the train set is 2888.326888 and the mse on the test set is 2858.255153.
