Humanity has made countless genetic changes to our food through practices such as grafting and selective breeding. What sets genetic modification using biotechnology apart from that practice? In your answer, offer your own summary (referencing the material from this course) on how genetic cloning is achieved.

Drilling down beneath a lake in Alaska yields chemical evidence of past changes in climate. Biological silicon, left by the skeletons of single-celled creatures called diatoms, measures the abundance of life in the lake. A rather complex variable based on the ratio of certain isotopes relative to ocean water gives an indirect measure of moisture, mostly from snow. As we drill down, we look farther into the past. Here are data from 2300 to 12,000 years ago:

(b) Find the single outlier in the data. This point strongly influences the correlation. What is the correlation with this point? (Round your answer to two decimal places.)


What is the correlation without this point? (Round your answer to two decimal places.)


(c) Is the outlier also strongly influential for the regression line? Calculate the regression line with the outlier. (Round your slope to two decimal places, round your y-intercept to one decimal place.)
ŷ =__________ − ___________ x

Calculate the regression line without the outlier. (Round your slope to two decimal places, round your y-intercept to one decimal place.)
ŷ = __________ − ___________ x

2. Runners are concerned about their form when racing. One measure of form is the stride rate, the number of steps taken per second. As running speed increases, the stride rate should also increase. In a study of 21 of the best American female runners, researchers measured the stride rate for different speeds. The following table gives the speeds (in feet per second) and the mean stride rates for these runners.

(b) Find the equation of the regression line of stride rate on speed. Draw this line on your plot. (Round your answers to four decimal places.)

(c) For each of the speeds given, obtain the predicted value of the stride rate and the residual. Verify that the residuals add to zero. (Round your answers to three decimal places.)

Physical training can lead to changes in muscle composition and properties of local motor neurons, both of which will alter our capabilities to carry out movements. Are the following statements about that type of plasticity of our motor system TRUE or FALSE?

Question 1:

How sensitive to changes in water temperature are coral reefs? To find out, scientists examined data on sea surface temperatures and coral growth per year at locations in the Red Sea. Here are the data: Sea surface temperature 29.69 29.86 29.95 30.3 30.51 30.68 30.87

Growth 2.63 2.57 2.62 2.47 2.27 2.37 2.27

Use your calculator to find: The mean (± 0.0001) and standard deviation (± 0.0001) for sea surface temperature: x¯¯¯= sx=

The mean (±0.0001) and standard deviation (± 0.0001) for coral growth: y¯¯¯= sy=

The correlation (± 0.0001) r = . The slope (± 0.01) of the equation of the least-squares regression line is b =

and the intercept is (± 0.01) a =

Using the model of loanable funds explain how the following changes affect the real interest rate, investment, consumption, and government expenditure. Include the appropriate diagram as part of your answer. Initially assume that consumption depends only on disposable income.

A)Expectations about the future profitability of investment improve. (Hint: For a given real interest rate, r, firms will invest a greater amount after expectations improve).

B) How does your answer to (A) change if consumption also depends on the real interest rate (i.e. is decreasing with r)?

Taxes are costs, and, therefore, changes in tax rates can affect consumer prices, project lives, and the value of existing firms. Evaluate the change in taxation on the valuation of the following project:

Assumptions: Tax depreciation is straight-line over three years. Pre-tax salvage value is 25 in year 3 and 50 if the asset is scrapped in year 2. Tax on salvage value is 40% of the difference between salvage value and book value of the investment. The cost of capital is 20%.

1. Please verify that the information given above yields NPV = 0.
2. If you decide to terminate the project in year two (2) what would be the NPV of the project?
3. Suppose that the government now changes tax depreciation to allow a 100% write-off in year one (1). How does this affect your answers to parts a and b above?
4. Would it now make sense to terminate the project after two rather than three years?
5. How would your answers change if the corporate income tax were abolished entirely?

Analyzing Operational Changes
Operating results for department B of Delta Company during 2016 are as follows:

If department B could maintain the same physical volume of product sold while raising selling prices an average of 15% and making an additional advertising expenditure of $60,000, what would be the effect on the department's net income or net loss? (Ignore income tax in your calculations.)

Use a negative sign with your answer to indicate if the effect increases the company's net loss.

If Department B increased its selling price by 15%, the effect on net income (loss) would be $Answer
