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?

The company has a traditional costing system in which manufacturing overhead is applied to units based on direct labor-hours. Data concerning manufacturing overhead and direct labor-hours for the upcoming year appear below:

Required:

1. Compute the product margins for the Xtreme and the Pathfinder products under the company’s traditional costing system.

2. The company is considering replacing its traditional costing system with an activity-based costing system that would assign its manufacturing overhead to the following four activity cost pools (the Other cost pool includes organization-sustaining costs and idle capacity costs):

Compute the product margins for the Xtreme and the Pathfinder products under the activity-based costing system.

3. Prepare a quantitative comparison of the traditional and activity-based cost assignments.

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"
