Tree height (m)
Histogram of trees by height in a sample of 500 trees. Binwidth = 0.5 m.
Answer:
0.002
A pharmaceutical company runs a trial of a drug designed to reduce high
blood pressure on a population of people with an average systolic blood
pressure of of 120 mm Hg, and a standard deviation of 20 mm Hg.
The company measures blood pressure once for 200 trial subjects, and only
gives the drug to 30 subjects with blood pressure measured above 140 mm
Hg. They do not give the drug to any of the remaining subjects.
If the drug is not actually effective at reducing blood pressure, how would
you predict the blood pressure of the subjects treated with the drug to change
on average when measured again one month later?
Select one:
a. The treated subjects will have higher blood pressure on average in the
second measurement
Pb. The treated subjects will have approximately the same blood
pressure on average in the second measurement
C. The treated subjects will have lower blood pressure on average in the
second measurement
