complete solution
Which of the following types of bias is most commonly associated with a case-
control study?
Recall bias
A new non-invasive screening test is proposed that is claimed to be able to
identify patients with impaired glucose tolerance based on a battery of questions
related to health behaviors. The new test is given to 75 patients. Based on each
patient's responses to the questions they are classified as positive or negative for
impaired glucose tolerance. Each patient also submits a blood sample and their
glucose tolerance status is determined. The results are tabulated below
What is the sensitivity of the screening test?
What is the false positive fraction of the screening test?
Sensitivity = #(true positives)/(#(true positives)+#(false negatives)) = 17/(17+8) = 17/25
= 0.68
Answer: 0.68
False positive fraction = #(false positives)/(#(false positives)+#(true negatives))
=13/(13+37)
= 13/50 = 0.26
Answer: 0.26
A study is designed to evaluate the impact of a daily multivitamin on students'

Five hundred people are enrolled in a 10-year cohort study. At the start of the
study, 50 have diagnosed CVD. Over the course of the study, 40 people who were
free of CVD at baseline develop CVD. What is the cumulative incidence of CVD
over 10 years?
A. Cumulative incidence of CVD over 10 years
Cumulative incidence 40/450=.0888 x 100=8.9%
B. The prevalence of CVD at base line
a. Prevalence baseline=50/500 .1 x 100= 10%
C. The prevalence of CVD at ten years is
a. Prevalence 10 year 90/500= .18 x 100=18%
What is the median blood glucose level of the following data set collected from 8
individuals: 89, 95, 99, 102, 107, 108, 111, and 119?
