Chapter 131. A financier whose specialty is investing in rock concerts has observed that, in general, concerts with "big-name" stars seem to generate more revenue than those concerts whose stars are less well known. Toexamine his belief, he records the gross revenue and the payment (in $ millions) given to the two highest-paid performers in the concert for ten concert tours.Concert1·234 56778910Cost of Two Highest PaidPerformers ($mil)5.37.21.31.83.52.68.02.44.56.7Gross Revenue($mil)48651820312673233958(1) Determine the standard error of estimate and describe what this statistic tells you about the regressionline.(2) Determine the coefficient of determination and discuss what its value tells you about the two variables.(3) Calculate the Pearson correlation coefficient. Interpret the results.(4) Conduct a test of the population coefficient of correlation to determine at the 5% significance levelwhether a positive linear relationship exists between payment to the two highest-paid performers andgross revenue.(5) Conduct a test of the population slope to determine at the 5% significance level whether a positivelinear relationship exists between payment to the two highest-paid performers and gross revenue.(6) Do the p and ₁ tests in the previous questions provide the same results?

If a company has excess capacity, it is contemplating whether a special order should be accepted. The order will not impact regular sales. If the company accepts the special order, what will occur? O Both fixed and variable costs will increase. Net income will increase if the special sales price per unit exceeds the unit variable costs. There are no incremental revenues. Incremental costs will not be affected.
4. Gursoy Furnitures sells office chairs ordered from its flagship store. It costs $100 to place an order, and the lead time is two weeks. Demand during lead time is N(40, 1.96). Gursoy Furnitures estimates that each stockout causes a loss of $50 in future goodwill. It pays $60 for each chair and sells it for $100. The annual holding a chair inventory is 30% of its purchase cost. a) Assuming that all demand is backlogged, what are the reorder point and the safety stock level? b) To meet 99% service objective, what should be the safety stock level for Type 1 Service? For Type 2 Service?
To the Internal Revenue Service (IRS), the reasonableness of total itemized deductions depends on the taxpayer's adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger th average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of itemized deductions follow.

Total DVD and Blu-ray disc sales in 2009 were $8.72 billion. For the purposes of this problem, you will combine DVD and Blue-ray disk sales into one category of DVD sales. A study by In-Stat predicted that "physical disc sales will decline by $4.7 billion by 2014," and that "streaming, on the other hand, should grow from its current $2.2 billion to $6.3 billion over the same time period (2009–2014). d. Write an equation that represents the linear model for streaming videos. Let S = the total sales of streaming videos in billions of dollars, and t = the number of years after 2009. e. In what year do the models predict streaming video sales to exceed DVD sales?
1. Redback Industries is a relatively small but successful and fast-growing maker of peripheral devices for cell phones including battery chargers, enhanced antennas, SIM cards, and custom carrying cases. Costco is considering purchasing Redback in order to sell the devices as private label offerings. However, Costco has set an offer price of $ 600M that depends on whether Redback’s current Annual Net Income is higher and significantly different from its 14-year average of $ 104.5M per year; Redback has indicated it is willing to sell itself to Costco at the $600M price. Use the following information to determine at the 95 % Level Of Confidence whether Costco will proceed with the purchase at the planned price of $ 600M or will lower its offering price if Redback’s current Annual Net Income is not greater than $ 104.5M per year. Redback Industries Normalized Yearly Annual Net Income over the last 14 years is $ 104.5M Redback Industries is currently reporting Yearly Annual Net…

Use Bartman Industries and Reynolds Incorporated's stock prices and dividends, along with the Market Index, shown below for the period 1997-2002 to answer the following questions Data as given in the problem are shown below: Bartman Industries Year 2002 2001 2000 1999 1998 1997 Stock Price $17.250 14.750 16.500 10.750 11375 7.625 Dividend $1.150 1.060 1.000 0.950 0.900 0.850 Reynolds Incorporated Stock Price $48.750 52.300 48.750 57.250 60.000 55.750 Dividend $3.000 2.900 2.750 2.500 2.250 2.000 Market Index Includes Divs. 11,663.98 8,785.70 8,679.98 6,434.03 5,602.28 4,705.97 a. Use the data given to calculate annual returns for Batman. Reynolds, and the Market Index, and then calculate average returns over the 5-year period. (Hint: Remember, returns are calculated by subtracting the beginning price from the ending price to get the capital gain or loss, adding the dividend to the capital gain or loss, and dividing the result by the beginning price. Assume that dividends are already…

You expect AGE to have a negative coefficient. Create and test the appropriate…
38. A real estate development company, Omega, Inc., is considering the purchase of one of three "packages" put together by its director of marketing. Each package contains a different combination of land acreage by type of land, zoning, and geographic location. The value of the investment will depend on which of four population growth patterns occurs in the next few years. The payoff table is given below (in millions): Plan Demand Low Medium High 4,500,000 4,000,000 3,500,000 3,000,000 2,000,000 4,250,000 2 4,750,000 4,250.000 5,000,000 7,500,000 12,500,000 4 3,500,000 a. Determine the Bayes decision, given the following probability density: P( S: ) - 0.20, P( $2 )-0.25, P( $ )-0.45, and P( S. )-0.10. b. Compute the expected value of perfect information. c. Suppose the marketing director spends P5,000,000 on market study and obtains some information, which we denote by I. The conditional likelihood probabilities of I are as follows: P( 1/s, -0.10, P( 11s, )-0.30, P( 11s, -0.35, PI 11s,…
3. Aquasystem performed a make/buy analysis to for making a new water filters. The filter sells for $50 that will require equipment that will cost $200,000 and $25,000 annual operating cost comprise the fixed cost. The variable cost is $20 per filter. The equipment has a 5 year life, no salvage value, and the MARR is 6% per year. The decision to make the filter was based on breakeven point and the historical sales level of 500 filter per year. a. Determine the breakeven point b. An engineer investigated that a supplier can make the filter for $30 each. Determine whether Aquasystem should make or buy the filters.
32. A hardware company sells a lot of low-cost, highvolume products. For one such product, it is equallylikely that annual unit sales will be low or high. Ifsales are low (30,000), the company can sell theproduct for $20 per unit. If sales are high (70,000),a competitor will enter and the company will be ableto sell the product for only $15 per unit. The variablecost per unit has a 20% chance of being $10, a 60%chance of being $11, and a 20% chance of being $12.Annual fixed costs are $20,000.a. Use simulation to estimate the company’s expectedannual profit.b. Find a 95% interval for the company’s annualprofit, that is, an interval such that about 95% ofthe actual profits are inside it.c. Now suppose that annual unit sales, variable cost,and unit price are equal to their respective expectedvalues—that is, there is no uncertainty. Determinethe company’s annual profit for this scenario.d. Can you conclude from the results in parts a and cthat the expected profit from a simulation is…
