Question 1 (5 points)

As a new graduate of UCW working for the Centre of Diseases in BC, you have been tasked to apply ML to analyze a new variant of an infectious disease. Your algorithm is designed to positively identify DX which can be mistaken for DY or DZ variants.

The dataset had 103, 648, and 702 samples of DX, DY, DZ respectively. The following confusion matrix is provided as a result of this model with ROC Area of 0.991.

nation

	Predicted
	DX Variant	DY Variant	DZ Variant
DX	88	7	8
DY	9	489	50
DZ	9	53	640

Use the confusion matrix above to answer the following questions.
