The scatter chart below displays 6 observations of a training set plotted according to the values of 2 quantitative variables (x₁ and x₂ expressed in the same units) that characterize the 6 observations. (The standardization of these values is not needed.) Three observations (#1, #2, #3) belong to Class 1, and the other three (#4, #5, #6) to Class 0. The chart also displays a new observation (#7) that must be classified using the k-NN method with the cutoff value of 0.5.

For k = 5, Observation 7 should be classified by k-NN in

	a.	Class 1
	b.	Class 0
	c.	both Class 0 and Class 1
	d.	neither Class 0 nor Class 1

The confusion matrix for a classification method with Class 0 and Class 1 is given below. What are the percent error rates for Class 0 and Class 1 ? a. 55.56% and 14.29%, respectively b. 33.81% and 12.69%, respectively c. 65.82% and 14.29%, respectively d. 43.25 and 36.67%, respectively
