2,620 men were enrolled in the study of prostate cancer and 930 of those had confirmed by biopsy prostate cancer. The sensitivity of the Prostate-Specific Antigen (PSA) test was 86% and the specificity was 33%. Calculate positive predictive value (PPV) and negative predictive value (NPV) of the PSA test given this information and interpret (explain) the results. (Show your calculations to get credit)
Answers
Answer:
81%
Explanation:
0.86 · 930 = 799.8 ⇒ 800 men
Other 130 men have negative PSA test
2620 - 930 = 1690 ⇒ 1690 without cancer
0.33 · 1690 = 557.8 ⇒ 558 men no cancer + negetive PSA tests
1690 - 558 = 1132
*view attachment below*
Positive perdictive value = 800/1932 = 0.42 = 42%
Negative predictive value = 558/688 = 0.81 = 81%.
The probability of not having prostate cancer among men with a negative PSA test is 81%

As a state epidemiologist, you are called upon to determine whether a recent oil spill in a water reservoir has caused an unusual type of acute arthritis. Within the county that you work, water is supplied by two independent reservoirs separated by 100 miles. The spill occurred in one of these reservoirs. The records from the Water Department clearly indicate which households receive water from which reservoir. Finally, you develop a case definition and institute a surveillance program to detect cases. To determine an association between the oil spill and arthritis, would you perform a cohort study or case-control study
Answers
ANSWER: CASE-CONTROL STUDY

Case-control Study provides an observational experiment between two existing groups (two reservoirs) differing in outcome (affected and not affected), they are highlighted and compared on the basis of a context (disease outbreak; arthritis).
However, the known group is regarded as the control group and it provides a substantial guide to the confirm the validity of other experimental groups in relation to the general context (outbreak of arthritis).

1. Always look like you're paying attention and are on track. Pretend you're taking notes. Work on a homework for a different class, write a poem or story, or just write random things. Try to avoid drawing or doodling, cause most teachers can see that it isn't writing from across the room.
2. When your teacher keeps calling on you and embarrassing you with difficult questions, try rephrasing the question before you answer it. She/he may not realize you don't understand the material and might just think you haven't been doing the work.
I have much right now but if you look at it in the teacher's perspective, the teacher is just doing their job. Try to do good in class, kill them with kindness, and just chill, maybe joke with them. Maybe they'll be nicer and more fun.
