A Researcher Studying the Effect of Price Cuts on Consumers

A researcher studying the effect of price cuts on consumers' expectations makes up two different histories of the store price of a hypothetical brand of laundry detergent for the past year. Eight students in a business class view one or the other price history on a computer. Some students see a steady price, whereas others see regular sales that temporarily cut the price. Students are asked the price they would expect to pay. The response is:

A) the laundry detergent.
B) the eight business students.
C) the price the students would expect to pay.
D) the sale prices.
