From “The Practice of Statistics in the Life Sciences” by Baldi
and Moore. Obesity in adult males is associated with lower levels
of sex hormone. A study investigated a possible link between
obesity and plasma testosterone concentrations in adolescent males
between the ages of 14 and 20 years. Here are the data for 25 obese
adolescent males, measured in nanomoles per liter of blood
(nmol/l): 0.30 0.24 0.19 0.17 0.18 0.23 0.24 0.06 0.15 0.17 0.18
0.17 0.15 0.12 0.25...

Find/discover an example of statistics & probability in the
news to discuss the following statement that represents one of the
objectives of statistics analysis: "Statistics and Probability help
us make decisions based on data analysis." Briefly discuss
how the news item or article meets this objective. Cite
your references. Also, keep in mind and discuss how the impact of
your study on your patients or staff might differ if you found it
in a journal.

From ”The Basic Practice of Statistics” by Moore. Many people
who come to clinics to be tested for HIV don’t come back to learn
the test results. Clinics now use ”rapid HIV tests” that give a
result while the client waits. In a particular clinic use of rapid
tests increased the percent of clients who learned their test
results from 69% to 99.7%.
The trade-off for fast results is that rapid tests are less
accurate than slower laboratory tests. Applied...

In the “Probable Error of a Mean” by William Gossett the
following example was used. Yields of corn in pounds per acre were
calculated for kiln-dried seed and seed that was not dried. (It was
believed in the day that kiln-dried seed produces a higher yield).
The yield values for dried seed were:
2009, 1915, 2011, 2463, 2180, 1925, 2122, 1482, 1542, 1443,
1535
The yields achieved with regular seed were:
1903, 1935, 1910, 2496, 2108, 1961, 2060, 1444, 1612,...

Find the indicated confidence interval. Assume the standard
error comes from a bootstrap distribution that is approximately
normally distributed.
a) A 99% confidence interval for a proportion p if the sample
has n=400 with p^=0.80, and the standard error is SE=0.02.
b) A 95% confidence interval for a difference in proportions
p1-p2 if the samples have n1=50 with p^1=0.67 and n2=90 with
p^2=0.57, and the standard error is SE=0.08.
