2. A manufacturer of big screen smart TVs ships them in lots of
1000 TVs per lot. Before shipment, 30 TVs are randomly selected
from each lot and tested. If none is defective, the lot is shipped.
It is known that each TV has a probability of 0.005 of being
defective independent of each other TV.
A. What is the exact distribution of X, the number of defective
TVs in the 30 sampled TVs?
B. Find the exact probability of...

High blood pressure (hypertension) is a leading cause of
strokes. Medical researchers are constantly seeking ways to treat
patients suffering from this condition. A specialist in
hypertension claims that regular aerobic exercise can reduce high
blood pressure just as successfully as drugs, with none of the
adverse side effects. To test the claim, 50 patients who suffer
from high blood pressure were chosen to participate in an
experiment. For 60 days, half the sample exercised three times per
week for...

Many Americans have high blood pressure which can lead to a
number of serious conditions including heart attack and stroke.
There are a number of drugs available to treat high blood pressure,
but researchers are always seeking new ones with fewer side
effects. In this experiment, researchers randomly selected 20 women
from a pool with high-normal blood pressure to high blood pressure
and measured their initial systolic blood pressure (in mm of Hg).
They treated the subjects with an experimental...
