b. Explain using an example (use some made-up numbers for any type of products, you can use some numbers given on lecture slides too or any cross tabs you can find for a pair of products) why computing lift ratio is better in assessing soundness of an association rule than just using support for the products associated in the rule or confidence in the rule. What is the practical significance of lift ratio less than 1? b.
