The New York State Health Department reports a 10% rate of the HIV virus for the "at-risk" population. In one region, an intensive education program is used in an attempt to lower that 10% rate. After running the program, a follow-up study of 150 at-risk individuals is conducted. a) Assuming that the program has no effect, find the mean and standard deviation for the number of HIV cases in groups of 150 at-risk people. b) Among the 150 people in the follow-up study, 8% (or 12 people) tested positive for the HIV virus. If the program has no effect, is that rate unusually low? Does this result suggest that the program is effective?

Transcribed Image Text:The New York State Health Department reports a 10% rate of the
HIV virus for the "at-risk" population. In one region, an intensive
education program is used in an attempt to lower that 10% rate.
After running the program, a follow-up study of 150 at-risk
individuals is conducted.
a) Assuming that the program has no effect, find the mean and
standard deviation for the number of HIV cases in groups of
150 at-risk people.
b) Among the 150 people in the follow-up study, 8% (or 12
people) tested positive for the HIV virus. If the program has
no effect, is that rate unusually low? Does this result suggest
that the program is effective?
