Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups.

1.     Paste the relevant SPSS output. (2 pt)

2.     Create an appropriate graph to display this data (make sure you have labels on both x and y axes). (2 pts)

3.        Write an APA-style Results section based on your analysis. All homework “Results sections” should follow the examples provided in the presentations and textbooks. They should include the statistical statement within a complete sentence that mentions the type of test conducted, whether the test was significant, and if relevant, effect size and/or post hoc analyses. Don’t forget to include a decision about the null hypothesis. (3 pts)

The Yoran Yacht Company (YYC), a prominent sailboat builder in Newport, may design a new 30-foot sailboat based on the "winged" keels first introduced on the 12-meter yachts that raced for the America's Cup.

First, YYC would have to invest $14,000 at t = 0 for the design and model tank testing of the new boat. YYC's managers believe there is a 60% probability that this phase will be successful and the project will continue. If Stage 1 is not successful, the project will be abandoned with zero salvage value.

The next stage, if undertaken, would consist of making the molds and producing two prototype boats. This would cost $500,000 at t = 1. If the boats test well, YYC would go into production. If they do not, the molds and prototypes could be sold for $100,000. The managers estimate that the probability is 80% that the boats will pass testing and that Stage 3 will be undertaken.

Stage 3 consists of converting an unused production line to produce the new design. This would cost $1 million at t = 2. If the economy is strong at this point, the net value of sales would be $3 million; if the economy is weak, the net value would be $1.5 million. Both net values occur at t = 3, and each state of the economy has a probability of 0.5. YYC's corporate cost of capital is 11%.

1. Assume this project has average risk. Construct a decision tree and determine the project's expected NPV. Do not round intermediate calculations. Round your answer to the nearest cent.

Let x be the number of different research programs, and let y be the mean number of patents per program. As in any business, a company can spread itself too thin. For example, too many research programs might lead to a decline in overall research productivity. The following data are for a collection of pharmaceutical companies and their research programs.

Complete parts (a) through (e), given Σx = 90, Σy = 8, Σx² = 1420, Σy² = 11.58, Σxy = 112.6, and

r ≈ −0.925.

(a) Draw a scatter diagram displaying the data.

(b) Verify the given sums Σx, Σy, Σx², Σy², Σxy, and the value of the sample correlation coefficient r. (Round your value for r to three decimal places.)

(c) Find x, and y. Then find the equation of the least-squares line  = a + bx. (Round your answers for x and y to two decimal places. Round your answers for a and b to three decimal places.)

(d) Graph the least-squares line. Be sure to plot the point (x, y) as a point on the line.

(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 to three decimal places. Round your answers for the percentages to one decimal place.)

(f) Suppose a pharmaceutical company has 13 different research programs. What does the least-squares equation forecast for y = mean number of patents per program? (Round your answer to two decimal places.)
patents per program

Can someone provide guidance for g-i for the following question? Someone already responded to a-f. Age (years) Amount of Activity (hours) 7 4.3 9 3.2 10 1.0 13 1.5 12 1.2 15 0.8 9 3.0 12 4.0 15 1.5 14 1.9

A psychologist believed that as children get older, they engage in more “inactive activities” such as playing computer games, watching TV and surfing the internet. She collected data from 10 children. She recorded the age of each child and the amount of activity (in hours) the child engaged in per week. The table below gives the data for this hypothetical study (it is also available in activity.txt).

a. Using R, obtain a scatterplot of the data. Discuss the relationship between age and activity based on the scatterplot.

b. Using R, obtain the simple linear regression linear regression line predicting activity from age.

c. Interpret the intercept and slope of the regression line

d. By hand, predict the amount of activity for age = 14

e. By hand, calculate the residual for age = 14

f. Using R output, test the null hypothesis that the slope coefficient is zero using the p-value approach. Write one sentence interpreting the meaning of this result. Make sure to report the test statistic and p-value.

g. Using R, obtain and report the 95% CI for the slope coefficient. Explain how we can use it to make a decision about the null hypothesis from part (f).

h. Using R output, test the null hypothesis that the population coefficient of determination is zero using the p-value approach, and write one sentence interpreting your result. Make sure to report the test statistic and p-value.

i. How do the test statistics in (f) and (h) mathematically relate to each other?

5. The public debt - ownership

The following table contains approximate figures for gross domestic product (GDP) and the national debt in the United States for June 2001 and June 2010. The national debt represents the total amount of money owed by the federal government to holders of U.S. securities. All numbers are in trillions of dollars.

Source: “U.S. Treasury, Bureau of Economic Analysis.”

The net national debt is the portion of the national debt held outside the federal government (government agencies and the Federal Reserve System). In June 2001, the net national debt as a percentage of total national debt was  "50.3" "47.4" "50.8" "55.1" %?

In June 2001, the percentage of the U.S. national debt held by foreigners was "17.5" "18.9" " 18.0" "19.6" %?

The fraction of the national debt held by foreigners will eventually need to be repaid to foreigners, thereby reducing the collective purchasing power of Americans. Between 2001 and 2010, the fraction of the national debt held by foreigners "Decreased" or "Increased"

The absolute level of the debt does not necessarily provide a clear indication of a nation's debt burden. Thus, economists often look at relative measures of the national debt. One possible relative measure of the national debt is the net national debt as a percentage of GDP. In 2001, the net national debt was "26.7" "44.9" "49.7" "49.2" %   of GDP. Between 2001 and 2010, the net national debt as a percentage of GDP "Increased" or "Decreased"
