Textbook Question

Chapter 8.5, Problem 12MS

De-lines of defense. Using the payoff matrix in Mindscape 7, plot two points on the axes to the right as follows. First, let the probability the offense passes be 0 and suppose the defense defends against a run. Plot the point showing the gain for the offense. Then, let the probability the offense passes be 1 and suppose the defense defends against a run. Plot the point showing the gain for the offense. Draw the line through the two points to show the average offensive gain when the defense defends against a run depending on the probability the offense passes. If you did Mindscape 10, how does your answer there relate to this line?

depending The owner of a chain of mini-markets wants to compare the sales performance of two of her stores, Store 1 and Store 2. Sales can vary considerably on the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same 12 days, chosen at random. She records the sales (in dollars) for each store on these days, as shown in the table below.

When homeowners list their home for sale, they begin by listing it for a price that is greater than what they expect to receive. The longer a home is on the market, without being sold, the more the price drops. A realtor selects 50 homes that are currently listed for sale. A scatterplot reveals that the association between x = the number of days the home is on the market and y = the current asking price ($) is fairly linear and can be modeled by the equation \hat{y} = 245,000-200xy^=245,000−200x. Additionally, 85.4% of the variation in the current asking price can be explained by this linear model. Which of the following is the value of the correlation (r) for the relationship between x and y? (A) -200−200 (B) -0.924−0.924 (C) 0.1460.146 (D) 0.8540.854 (E) 0.9240.924
