Q2: Solve the KNN. We have data from the questionnaires survey (to ask people opinion) and objective testing with two attributes (acid durability and strength) to classify whether a special paper tissue is good or not. Here is four training samples \begin{tabular}{lcc} \multicolumn{2}{l}{X2 = Strength } \\ ( Acid Durability (seconds) & (kg/ square meter) \\ Y & 7 & Bad \\ 7 & 4 & Classification \\ 7 & 4 & Bad \\ 3 & 4 & Good \\ 1 & & Good \end{tabular} Now the factory produces a new paper tissue that pass laboratory test with X1=3 and X2=7. Without another expensive survey, can we guess what the classification of this new tissue is
