Explanation:

In a regression analysis, the predictor variable (also known as the independent variable) is used to predict the response variable (also known as the dependent variable). Here, the goal is to relate the length of newborn boys to their weight. So, the length is used to predict the weight.

Answer:

The predictor variable is length in units of cm and the response variable is weight in units of kg.
