PLease answer Question 4 i gave a question 1 information below just for a reference

Question#4): Use only the “Hungry”, “Type” and “Output” columns form the table from
Question 1 for this problem.
a) Perform one-hot encoding on suitable columns to transform the dataset.
b) Implement the k nearest neighbor classifier with k = 3, to classify the
following samples. Show your work.
sample 1: [Hungry = “Yes” , Type = “Thai”]
sample 2: [Hungry=”No”, Type=”French”]

Question1): Given the following dataset
Restaurant waiting: the problem of deciding whether to wait for a table at a
restaurant.
For this problem the output, y, is a Boolean variable that we will call WillWait.
The input, x, is a vector of ten attribute values, each of which has discrete
values:
1. Alternate: whether there is a suitable alternative restaurant nearby.
2. Bar: whether the restaurant has a comfortable bar area to wait in.
3. Fri/Sat: true on Fridays and Saturdays.
4. Hungry: whether we are hungry right now.
5. Patrons: how many people are in the restaurant (values are None, Some, and
Full).
6. Price: the restaurant’s price range ($, $$, $$$).
7. Raining: whether it is raining outside.
8. Reservation: whether we made a reservation.
9. Type: the kind of restaurant (French, Italian, Thai, or burger).
10. WaitEstimate: host’s wait estimate: 0–10, 10–30, 30–60, or >60minutes

Please show work and equations etc. no cdoing required ..

A): [Alt = “Yes” , Bar = “ No” ]
B): [ Alt = “Yes”, Bar=” No”, Price = “$”.
