Solution
so young buyers and old buyers spend same amount of money. (50 each). so age does not make a difference in amount of money spent
people of short time shopping and people of long time shopping also spend same amount of money. (50 each). so Length of time does not make a difference in amount of money spent
hence Neither age nor length of time makes a difference in amount of money spent.
but these interpretations say nothing about the interaction between time of shopping and age of shopper.
when young buyers shop for short time they spend 40 amount of money but the old buyers spend 10 amount.
whereas when young buyers shop for long time they spend 10 amount of money but the old buyers spend 40 amount
hence Younger buyers spend more money when they shop for a shorter time
whereas older buyers spend more money when they shop for a longer time
so option C is the most consistent with scenario C [answer]
| short | long | total | |
| young | 40 | 10 | 50 |
| old | 10 | 40 | 50 |
| total | 50 | 50 | 100 |
