Which interpretation is MOST consistent with the interaction effect in Scenario B?

A. If there is only a short time to shop, age makes no difference, but if
there is a long time to shop, younger buyers spend more money than older buyers.

B. Younger buyers spend more money in general than older buyers.

C. More money is spent when people shop for a long time as compared with a

SCENARIO A SCENARIO B SCENARIO C Short Long Short Long Short Long Young 40 10 25 Young 25 25 25 Young15 45 30 10 25 Old 15 15 15 Old 15 15 15 Old 40 25 20 20 15 30 25

Solution

so young buyers have spent 60 amount of money whereas the older ones have spent 30 amount.

people shop for a long time spent 60 amount of money whereas shopping for short time spent 30 amount of money.

but these two interpretations do not say anything about interaction effect.

now, when there is short time to shop the young and the old spent same amount of money. (15 each)

for long time to shop, young buyers spent more money than older buyers. (young spent 45 amount and old spent 15 amount)

hence option A is the most consistent with the interaction effect in Scenario B [answer]

	short	long	total
young	15	45	60
old	15	15	30
total	30	60	90
