This problem refers to Question 53 to 55. Randy Espinosa has just been fired as the university bookstore manager for setting prices too low (only 20 percent above suggested retail). He is considering opening a competing bookstore near the campus, and he has begun an analysis of the situation. There are two possible sites under consideration. One is relatively small, while the other is large. If he opens at Site 1 and demand is good, he will generate a profit of PhP50,000. If demand is low, he will lose PhP10,000. If he opens at Site 2 and demand is high, he will generate a profit of PhP80,000, but he will lose PhP30,000 if demand is low. He also has the option of not opening at either site.
He believes that there is a 50 percent chance that demand will be high. A market research study will cost PhP5,000. The probability of a good demand given a favorable study is 0.8.
