 The result of this computation shows that 3 of the 5 nearest neighbors to our new observation are
-malignant ("M"); since this is the majority, we classify our new observation as malignant. 
+malignant (`M`); since this is the majority, we classify our new observation as malignant. 
 These 5 neighbors are circled in Figure \@ref(fig:05-multiknn-3).
