"A study was conducted to evaluate new test for human papilloma virus (HPV). One hundred fifteen women with HPV were compared to 426 women who did not have HPV. A total of 97 women tested positive using the new test, 81 of whom really did have HPV.
You will be graded on calculations (including completion of the 2x2 table as shown in class and showing your work for calculation, your interpretations, and your answers to the other questions. Your interpretations must be specific and will be graded on accuracy, correct use of scientific terminology, professional writing style, grammar and spelling."
a) Complete a contingency table
b) How many women are in each of the following categories?
True positives:
False positives:
True negatives:
False negatives:
c) Calculate and interpret the sensitivity of the new screening test.
d) Calculate and interpret the specificity of the new screening test.
e) Calculate and interpret the positive predictive value of the new screening test.
f) Calculate and interpret the negative predictive value of the new screening test.
g) Do you think that it would be better to use this new screening test for HPV or an older screening test with 90% sensitivity and 80% specificity. The older screening test is more expensive. Write 75-100 words supporting your position.

A randomized experimental study was conducted to evaluate the
effectiveness of a new cancer vaccine. One-thousand healthy adults
were randomized to receive either the new vaccine (500 adults) or
the old vaccine (500 adults). The adults were followed for 10 years
to monitor the incidence of colon cancer. At the end of the study,
the risk ratio for developing colon cancer was 0.5 among the adults
who received the new vaccine compared to adults who received the
old vaccine. The...

A screening examination was performed on 250 persons for human
papilloma virus (HPV), which is found in cervical cancer. A
definitive diagnosis for cervical cancer among the 250 subjects had
been obtain previously. There were 60 subject who tested positive
for HPV who also had cervical cancer, 40 subjects who tested
positive for HPV but did not have cervical cancer. There were 10
subjects who tested negative for HPV, but had cervical cancer and
140 subjects who tested negative for...

A very large trial was conducted to combat the Human
Papillomavirus (HPV) on 402,245 consenting adults. 201,867 of the
patients were given an experimental vaccine (the treatment group),
and 200,378 of them were administered placebos (the placebo group).
In the treatment group 41 people contracted HPV, and in the placebo
group 124 people contracted HPV. a) Use a 5% significance level to
test the claim that this vaccine is effective, and b) create a
confidence interval for testing. (Follow all...

Human papilloma virus (HPV) is the most common sexually
transmitted infection, with 45% of 20-24 yr old women infected.
Infection of the genitalia and cervix with HPV increases the risk
of cervical cancer 10-fold. Two proteins encoded by HPV DNA bind to
p53 and Rb. Which of the following do you think would Best describe
the function of those two HPV proteins?
proto-oncogenes
oncogenes

A study was conducted to explore the effects of ethanol on sleep
time. Fifteen rats were randomized to one of three treatments.
Treatment 1 got only water (control). Treatment 2 got 1g of ethanol
per kg of body weight, and treatment 3 got 2g/kg of ethanol. The
amount of REM sleep in a 24hr period was recorded, in minutes. Data
are below:
Treatment 1: 63, 54, 69, 50, 72
Treatment 2: 45, 60, 40, 56
Treatment 3: 31, 40, 45,...
