Hi, you just have to multiply the expected earnings by the probability of occurance of a certain event and then add up all the products. Here is the information all organized to be processed.
Item                  Prob	Earn
Booming           20%	-6%
Normal           55%	7%

Ok, now let´s calculate the expected rate of return.

Answer:
False
Explanation:
A lagged effect in marketing can be defined as the delay that comes from an effort put into marketing a product. 
In marketing, efforts put into an advertisement can yield a greater result even after the lag period. This means that a product might need more than one advertisement and the combined effects of the advertisements will be seen overtime if not immediately. 
In the above question, Joel still went on to get a Ford fusion after seeing the Toyota advert which means that something from his research must have influenced his decision. Either price, quality, or any other factors must have been responsible for Joel's choice but it is definitely not the lagged effect. 
Cheers.
