Question 1. A researcher wants to study the effect of a price change on the sales of various brands of a certain product. Assume the market is made up of four brands -W, X, Y and Z- and the price change (decrease) for brand W is introduced immediately after time tO. Assume every respondent buys exactly one unit of the product in each period. Data on number of respondents buying each brand in each period, based on a panel, are as follows: W Y W 175 25 100 25 25 to Y 25 50 50 25 Note: Confine your attention only to the data presented Assume the world starts at to after ti and the strategies of brands X, Y, and Z are unchanged between to and ti. and stops c) Which brand(s) other than W exhibited the highest loyalty rate? Show your calculations. d) Which of the brands X, Y, Z should be most worried about W's promotion? Show calculations. your

Mariah Jacobsen is the marketing manager at ABC Electronics, a major consumer electronics supplier in the northwest. Over the last five years, sales of the company's flagship product - the Wizer Anonymizer (the WA) - have been 45000, 45500, 44500, 46000 and 44000 units. This rate of sales is considered average for the product over the last twenty years or so. Ms. Jacobsen believes that the distribution of the WA's sales is normal with a standard deviation of 1500 units. If she were asked to make a forecast of next year's sales to upper management, what is the likelihood that she would be correct if she predicts sales between 43000 and 46000?
