Two groups, A and B, of arthritis sufferers are given a placebo
and a prescription drug respectively for a period of one month.
Then, the time in seconds taken to walk 10 yards is measured.
The measured times in the two groups are A[1], ... ,A[m] and
B[1] , ... , B[n] .
It is required to test the hypothesis H[0] :
mu=nu where mu and nu denote respectively the mean
walking times in the (hypothetical) populations of sufferers

We are testing a new prescription drug that cures the common
cold. One of the side effects of the drug is insomnia (can’t
sleep). There is a 6% chance the patient will develop insomnia. We
have selected 50 people and administered the drug to them and asked
if they developed insomnia. Define the random variable x to be the
number of people who develop insomnia.

Drug Testing
A company has 20,000 employees to drug test. We are going to
assume there are 500 actively using illegal drugs. The drug test
they are going to administer is 95% accurate.
Test is Positive
Test is Negative
Total
Actively Using
Not Using
Total
20,000
If someone tests positive for drugs, what is the probability the
person is actually NOT taking drugs?
If someone tests negative for drugs, what is the probability the
test is wrong?...

You are a graduate student testing a new drug (drug G) that
reduces cocaine addiction in mice. You want to find out what the
pharmacological action of drug G is, and you know that it involves
monoaminergic signaling, but you don’t know more about it than
that. You have found a monoaminergic synapse whose signaling is
affected by drug G. You can stimulate the presynaptic neuron at
this synapse and record the resulting EPSPs in the postsynaptic
neuron. This synapse...

Ten epileptic patients participated in a study of a new
anticonvulsant drug, valproate. During an 8-week placebo
period, the number of epileptic seizures were counted for each
patient. After this, each patient was then given Valproate, and
seizure counts were made during a second 8-week
period. The number of seizures are given below:
