Explanation:

A predictor variable is the one used to predict or explain changes in another variable, while a response variable is the one being measured or affected. Here, the number of rainy days is the variable that could influence how many books are checked out, so it acts as the predictor. The number of books checked out is the variable that responds to the number of rainy days, so it is the response variable.

Answer:

The predictor variable is number of rainy days
The response variable is number of books
