Possible minor typos in PS9

@rickecon Hi Rick,

In (b) logistic regression, we should tune the parameters penalty and C instead of max depth, min samples split, and min samples leaf.

In (c) random forest, n_estimators are the number of trees in the forest. I think it makes more sense to use sp_randint(10,200) instead of [10,200]. If using [10,200], we are only alternating between two values. However, this will add much more computing complexity and not guaranteed to get the best score because of the randomness.

In (d) SVC, shrinking need to be a boolean value, so it could be either [True, False] or [1,0] (this is corrected in class).

Yes, in part (b), I accidentally left that line in from some text I copied from another part.

Yes, in part (c), n_estimators should be a sp_randint. I also reset max_depth to be a `sp_randit.

Yes. fixed the boolean in part (d).
