(a) The table below shows the length and weight measurements recorded during a study involving alligators and crocodiles. Assuming k=3, use the k-nearest neighbour algorithm (using the Euclidean distance) to determine whether the reptile with body length 2.4m and tail length 1.8m is an alligator or a crocodile.

The information recorded is for 14 customers who did or did not subscribe to a new magazine. The other attributes recorded are the customers' age, their income, their gender and whether or not they own their home. Use the ID3 algorithm with log10 to build a decision tree to decide if a customer satisfying the criteria { age >40, income = high, gender = male, owns their home = no } is likely to subscribe to the new magazine.
