We are evaluating a project that costs $520,000, has a life of 6 years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 73,000 units per year. Price per unit is $45, variable cost per unit is $30, and fixed costs are $840,000 per year. The tax rate is 21 percent, and we require a retum of 15 percent on this project. Suppose the projections given for price, quantity, variable costs, and fixed costs are all accurate to within ±10 percent. Calculate the best-case and worst-case NPV figures. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) Best-case NPV Worst-case NPV McGilla Golf is evaluating a new line of golf clubs. The clubs will sell for $1,040 per set and have a variable cost of $470 per set. The company has spent $167,500 for a marketing study that determined the company will sell 52,500 sets per year for seven years. The marketing study also determined that the company will lose sales of 9,900 sets of its high-priced clubs. The high-priced clubs sell at $1,540 and have variable costs of $670. The company also will increase sales of its cheap clubs by 12,500 sets. The cheap clubs sell for $470 and have variable costs of $200 per set. The fixed costs each year will be $9,850,000. The company has also spent $1,275,000 on research and development for the new clubs. The plant and equipment required will cost $32,550,000 and will be depreciated on a straight-line basis to a zero salvage value. The new clubs will also require an increase in net working capital of $2,650,000 that will be returned at the end of the project. The tax rate is 21 percent, and the cost of capital is 15 percent. Suppose you feel the units, price, variable cost, and fixed costs are accurate to within only ±10 percent. What are the best-case and worst-case NPVs? (Hint: The price and variable costs for the two existing sets of clubs are known with certainty, only the sales gained or lost are uncertain.) (A negative amount should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) Best-case Worst-case

At a large public state college in Virginia, the mean Verbal SAT score of all attending students was mu = 600 with a population standard deviation: sigma = 96. A random sample of 64 students is selected from the population of students. What is the probability that the sample mean Verbal SAT score for the 64 students is at most 620?

Part 2: Drag coefficients We could use the same process to obtain a quadratic or higher polynomial fit to data. If we try to fit an n degree polynomial, the software has to solve an n by n linear system, which is easily done. This is what Matlab basic fitting tool uses to obtain an n degree polynomial fit whenever the number of data points is more than n + 1. Drag due to air resistance is proportional to the square of the velocity, i.e. $f_a = kv^2$. In a wind tunnel experiment the velocity $v$ can be varied by setting the speed of the fan and the drag can be measured directly (it is the force on the object). In this and every experiment some random noise will occur. The following sequence of commands replicates the data one might receive from a wind tunnel: (In the following d is the last two digits of your student ID. For example if your ID is 207005123 then d = 23 or if your ID is 207005102 then d = 2) > d = input('last two digits of your studentID : ') > v = 0:.2:(sqrt(d)+25); > fd = .1234*v.^2; > fdrandom = fd + .4*v.*randn(size(v)); % randomize fd and call it fdrandom 1) Plot v versus fdrandom with red circles 2) The plot should look like a quadratic, but with some noise. Using the tools menu, add a quadratic fit and enable the show equations option. Do not forget to increase the significant figures. 3) What is the coefficient of x^2? How close is it to 0.1234? Note that whenever you select a polynomial in Matlab with a degree less than n-1 Matlab will produce a LEAST SQUARES FIT.
