Suppose you want to predict sneaker sales on the basis of advertising expenditures and sneaker color, red or blue. You create one dummy variable for the sneaker color (Red = 1 for red sneakers and Red = 0 for blue sneakers) and run the regression on data collected over ten years using the dummy variable and advertising expenditures as your independent variables. The equation you obtain is:

Sales = 631,085 + 533,024(Red) + 50.5(Advertising)

a. How would you interpret the regression model?

b. How would you interpret the coefficient for red sneakers?

New team of management has taken over. as a result, organizational changes from a country-club style leadership where everyone does whatever they want has changed to a more mechanistic, structured, top-down management style. what ethical issues should the employees consider and how should they go about addressing these?

Suppose that xtel currently is selling at $40 per share. you buy 500 shares using $15,000 of your own money, borrowing the remainder of the purchase price from your broker. the rate on the margin loan is 8%. a. what is the percentage increase in the net worth of your brokerage account if the price of xtel immediately changes to (a) $44; (b) $40; (c) $36? (leave no cells blank - be certain to enter "0" wherever required. negative values should be indicated by a minus sign. round your answers to 2 decimal places.) b. if the maintenance margin is 25%, how low can xtel’s price fall before you get a margin call? (round your answer to 2 decimal places.) c. how would your answer to requirement 2 would change if you had financed the initial purchase with only $10,000 of your own money? (round your answer to 2 decimal places.) d. what is the rate of return on your margined position (assuming again that you invest $15,000 of your own money) if xtel is selling after one year at (a) $44; (b) $40; (c) $36? (negative values should be indicated by a minus sign. round your answers to 2 decimal places.) e. continue to assume that a year has passed. how low can xtel’s price fall before you get a margin call? (round your answer to 2 decimal places.)

Which of the following is one of the advantages primarily associated with a performance appraisal? (a) it protects employees against discrimination on the basis of race.
