The table below give data on an exposure of interest in a population and the numbers of people with the disease/outcomes. Answer the following questions on PAR for this population (4.5 points).
|
Exposure |
Total Pop. |
Outcome Present |
|
Present |
50,000 |
10,000 |
|
Absent |
250,000 |
2,000 |
- What is the prevalence of exposure?
- What is the prevalence of non-exposure?
- What is the risk of the disease or outcome in the exposed?
- What is the risk of the disease or outcome in the unexposed?
- What is the risk of the disease or outcome in the total population? (You may want to wait on rounding the previous answers until you calculate this)
- What is the population attributable risk (PAR)?
- What is the percent population attributable risk?
- What happens to the Percent PAR as the exposure prevalence declines in the above example? Explain why

The table below shows data on population and expenditures in
five countries, as well as the value of home production, the
underground economy, and environmental externalities in each. Note
all figures are expressed in millions of dollars.
a. Calculate GDP and GDP per capita in each
country.
b. Calculate the size of home production,
the underground economy, and environmental externalities in each
country as a percentage of GDP.
c. Calculate total and per capita “GDP
plus” in each country by...

The two data sets in the table below are dependent random
samples. The population of ( x − y ) (x-y) differences is
approximately normally distributed. A claim is made that the mean
difference ( x − y ) (x-y) is less than -31.4.

The table below represents data on a variable of
interest collected from a single sample. It is known that the
variable of interest has a mean of 10 and a standard deviation of 5
in the general population. A researcher is interested in testing
whether the population from which this sample was selected is
different from the general population.
