A new disease has annihilating amphibian populations at
unprecedented levels. Researchers has been trying to develop some
treatment that can counteract the disease and save some of the
amphibian populations. To test which of two potential solutions is
more effective, they take a sample of frogs and randomly divide
them into two groups. After being treated, 256 of the 400 frogs in
group 1 ended up surviving exposure to the pathogen; 300 of the 482
frogs in the second group survived. For the following questions,
calculate your difference in the order: group 1 - group 2. The
standard error of the difference was 0.033.
Calculate the Test statistic:
Calculate the p-value:

1. Assume researchers are trying to find out the mean
concentration levels of a specific drug in a population of
individuals’ blood during a clinical trail. The researchers find
that the sample population n= 100 has a mean concentration of 225
ng/mL with a standard deviation of 47 ng/mL. Calculate a 95%
confidence interval for the mean concentration level of the
medication for the population’s blood and interpret it.
[1] The researchers are 95.0% confident the true mean
concentration of...

Researchers have been trying to gauge the impact of the graying
of America. They report that currently 5% of the US population is
over the age of 75 and it is expected that in ten years, 15% of the
US population will be over the age of 75.
Will the shift result in higher mortality rates? Why or why
not?

You are working for a large pharmaceutical company that is
trying to develop new therapies to stop an aggressive form of
breast cancer. Your goal is to develop several different therapies
that seek to influence the abnormal control of cell cycle and
apoptosis in these cancerous cells. You’ve worked out a mechanism
to deliver your small molecules directly to the tumor, so that it
is only taken up by specific cells (cancerous cells), however you
are still working on your...

A new medical test has been designed to detect the presence of
the mysterious Brainlesserian disease. Among those who have the
disease, the probability that the disease will be detected by the
new test is 0.78. However, the probability that the test will
erroneously indicate the presence of the disease in those who do
not actually have it is 0.02. It is estimated that 19 % of the
population who take this test have the disease.
If the test administered...

Researchers have been studying the association between
cigarette smoking and caffeine intake and
Parkinson's Disease for more than 40 years. The results
of a study by Checkoway et al. (2002) follow:
Ever having smoked cigarettes resulted with an odds
ratio (OR) = 0.5 (95% confidence interval (CI):
0.4, 0.8).
The OR for current smokers was OR = 0.3 (95% CI: 0.1,
0.7).
Among ex-smokers the OR = 0.6 (95% CI: 0.4,
0.9).
Interpret the three ORs (in your own
words).

General Mills has been forced to develop new products to offer
to an increasingly demanding market. Traditional cereals and
packaged food products are not attractive to a more mobile and
demanding consumer. Technology, health/diet awareness, and
lifestyle have affected how and what consumers demand from the
grocery store.
GM’s kitchens have developed a breakfast meal which is highly
nutritious, can be heated in the microwave for 2 minutes, and can
be consumed while driving because of its unique packaging design....

A new industrial oven has just been installed at Piatt Bakery.
To develop experience regarding the oven temperature, an inspector
reads the temperature at four different places inside the oven each
half hour starting at 8:00 a.m. The last reading was at 10:30 a.m.,
for a total of six samples. The first reading, taken at 8:00 a.m.,
was 337 degrees Fahrenheit. (Only the last two digits are given in
the following table to make the computations easier.)

Question 3: For the last two decades, foreign direct investment
(FDI) has been offering an unprecedented opportunity for developing
countries to achieve faster economic growth. Through FDI, foreign
investors benefit from utilizing their firm-specific assets and
resources efficiently, such as technology and managerial know-how.
For capital-scarce developing economies, FDI implies access to not
only capital but also the benefit of acquiring advanced technology,
managerial expertise, employment productivity, human resource
development, global marketing networks, and best-practice systems
of corporate governance. In...
