Question $2(30$ points$).$ We have data from $7$ transactions at a local supermarket:

a$)$ Based on the table below, use the Apriori algorithm to find the frequent itemsets. Assume that

minimum support $s=2.(10$pts$)$

b$)$ Discover all association rules from the frequent itemsets identified in part a$)$ that have a

support of at least $42\%$ and a confidence of at least $0\mathrm{.}7.(10$pts$)$

c$)$ Calculate the interest of the rule$($s$)$ that you found in b$).(10$pts$)($Note: Calculate the

expectation of an item using the $\%$ that the item$)$
