1. In each store whose average customer age falls between 34 and 36, the number of self-check express lanes is above average. => TrueSort by age, btw 34 and 36 is A, F
Each has 8 Express lanes => more than avg (6.89)
2. There is a negative correlation between the number of self-check unlimited lanes and the average customer age. => TrueKeept sorting by age (ascending), the number of Unlimited lanes is in general descending
3. Stores in this table that have fewer self-check express lanes than the chain-wide average are less likely to have restaurants than stores that have more self-check express lanes than the chain-wide average. => FalseSort by Express lanes
- Those having fewer Express lanes than Avg is are I H C ==> all 3 have restaurants
- The remaining (have more Express lanes than Avg): most don't have
==> Should be MORE LIKELY rather than LESS LIKELY
