An economist is studying the job market in denver area neighborhoods. Let x represent the total number of jobs in a given neighborhood, and let y represent the number of entry-level jobs in the same neighborhood. A sample of six Denver neighborhoods Gave the following information (units in hundreds of jobs).
x 15 35 48 28 50 25
y 3 4 7 5 9 3
complete parts (a) through (e), given ∑x=201, ∑y=31, ∑x2=7663, ∑y2=189, ∑xy=1186, and r≈0,901.
a)draw a scatter diagram displaying the data
b) verify the given sums, ∑x, ∑y, ∑x2, ∑y2, ∑xy, and the value of the sample correlation coefficient r. ()round your value for r to three decimal value).
c) find the x-, and y- then find the equation of the least-squares line yˆ=a+bx. (round your answers for x- and y- to two decimal places. round your answers for a and b to three decimal places.)
e)find the value of the coefficient of determination r2. what percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line? what percentage is unexplained? (round your answer for r2 ro three decimal places. round your answers for the percentages to one decimal places.)
f) for a neighborhood with x=37 hundred jobs, how many are predicted to be entry level jobs? (round your answer to two decimal places.)

4. Expected dividends as a basis for stock values
The following graph shows the value of a stock’s dividends over time. The stock’s current dividend is $1.00 per share, and dividends are expected to grow at a constant rate of 2.70% per year. The intrinsic value of a stock should equal the sum of the present value (PV) of all of the dividends that a stock is supposed to pay in the future, but many people find it difficult to imagine adding up an infinite number of dividends.
Calculate the present value (PV) of the dividend paid today (D₀) and the discounted value of the dividends expected to be paid 10, 20, and 50 years from now (D10, D20, D50D10, D20, D50). Assume that the stock’s required return (rss) is 8.40%.
Note: Carry and round the calculations to four decimal places.
Time Period |
Dividend’s Expected Future Value |
Dividend’s Expected Present Value |
---|---|---|
Now | ||
End of Year 10 | ||
End of Year 20 | ||
End of Year 50 |
Using the orange curve (square symbols), plot the present value of each of the expected future dividends for years 10, 20, and 50. The resulting curve will illustrate how the PV of a particular dividend payment will decrease depending on how far from today the dividend is expected to be received.
Note: Round each of the discounted values of the dividends to the nearest tenth decimal place before plotting it on the graph. You can mouse over the points in the graph to see their coordinates.

A Wimax wireless network integrated with a satellite network can provide connectivity to any location within 10 km of the base station. The number of sectors per base station can be varied to increase the bandwidth. An independent cable operator is considering three bandwidth alternatives 44(Mbps), 55(Mbps), and 88 (Mbps). Assume a life of 20 years and a MARR of 10% per year.
Bandwidth Mbps |
First Cost, 1000$ | Operating Cost, 1000$ per Year | Annual Income, 1000$ per Year |
---|---|---|---|
44 | -40,000 | -2000 | +5000 |
55 | -46,000 | -1000 | +5000 |
88 | -61,000 | -500 |
+8000 |
1) Use incremental RoR analysis(IRR) and PW to determine the financially justified one.
2) Why should you use incremental Rate of return and what is the difference between that and MARR?

Think about Major League Baseball! The owners of the major league teams are arguing that they may have to shut the season down unless the players agree to a significant salary cut. If the players agree, the owners will be able to play games this season.
Explain loss-minimization and shut down cases for perfectly competitive firms. Explain why baseball owners may have to resort to a shut-down case and why they may be able to use a loss-minimization case.

Imagine you are a “dating consultant” who gives advice on how people can improve their odds of finding a person they can date and maybe have a satisfying long-term relationship with. Suppose a new client has recently hired you; Ralph a 35-year old chemical engineer. Using what you know about propinquity, similarity, and evolutionary psychology; provide advice to Ralph about the best things HE can do to attract a woman to be in a long-term relationship with him. Suppose another new client comes along later who is female. Does any of the advice you gave Ralph change for this female client? If so explain what you would tell her to do differently than Ralph and why.

B.) Farmers produce genetically modified avocado plants which allow for greater output without increasing costs.
C.) There is a large increase in the price of tomatoes, which is a complement of avocados.
D.) There is a significant increase in the price of water in California, where most U.S. avocados are grown
