Solution
The higher the lift ratio the stronger the association rule.
The lower the lift ratio the weaker the association rule.
Lift ration is the ratio of confidence of an association rule to the expected confidence.
The higher the confidence of the rule results in the higher lift ration which results in stronger the association rule.
Hence lift ratio is directly proportional to the association rule.
