Answer

There are 11 correctly predicted positives.

There are 1,033 false negatives.

Explanation

There are 11 correctly predicted positives.

TP = True Positive.

The class labels in the training set can take on only two possible values, which we usually refer to as positive or negative. The positive and negative instances that a classifier predicts correctly are called true positives (TP) and true negatives (TN), respectively. Similarly, the incorrectly classified instances are called false positives (FP) and false negatives (FN).

There are 1,033 false negatives.

FN = False Negative
