Group of answer choices

a. Regression and b. Classification

a. Clustering and b. Classification

a. Classification and b. Clustering

a. Classification and b. Regression

Answer 1

Answer: a. Classification and b. Regression

Explanation:

In part a, we have a Logistic (Binary) Classification wherein the Response Variable or the dependent variable(target) is categorical/ dichotomous i.e has two categories - Treated and Not Treated. In logistic classification Model, we predict the probabilities and then classify them into one of the two categories on the basis of probability cutoff.

In part b, the Response Variable is Continuous Variable, i.e. we are predicting the the time it takes for a person to be treated which is a continuous variable, hence, we use Regression Model
