In the following scenarios identify the Reality, the test, Sensitivity, Specificity, False Negative, and False Positive. Then explain which is worse (if either) a False Negative or a False Positive.

1. A Drug Test:

a. Reality:

b. Test:

c. Sensitivity:

d. Specificity:

e. False Negative:

f. False Positive:

g. Which is worse:

Expert Solution

Drug Test:

a. Reality : Person has actually taken the drug.

b. Test : Test correctly identifies the person as one who has taken the drug.

c. Sensitivity: Sensitivity is the proportion of people detected by the test as being drug taker, out of all the people who have actually consumed the drug.

d. Specificity : Sensitivity is the proportion of people detected by the test as NOT being drug taker, out of all the people who have actually NOT consumed the drug.

e. False Negative: It is the number of people detected by the test as NOT being drug taker, but who are actually drug takers.

f. False Positive : It is the number of people who are NOT actually drug takers but test identifies them as drug takers.

g. Objective of Drug test is to catch those people who have illegaly consumed the drug. Hence, False Negative is the worse than False positive.

Identify the following scenarios as either positive or negative externalities. a. You are a beekeeper. The neighboring farm uses a pesticide that harms your bees. b. You moved to the country for some peace and quiet. Your new neighbor is a hunter and does target practice all day long. c.

A newly developed test for coronavirus has sensitivity 0.90 and specificity 0.85. Sensitivity is the probability of a positive result given that a person has the virus, and specificity is the probability of a negative result given that a person has no virus. Suppose that 12% of the population has the coronavirus. If the test gives you a positive result, what is the probability that you actually have the virus? Show your work.

Suppose a test for a disease has a sensitivity of 80% and a specificity of 95%. Further suppose that in a certain country with a population of 1,000,000, 21% of the population has the disease. Fill in the accompanying table. -------------------Has disease |Does not have disease| Totals Test positive Test negative Totals

Suppose that a medical test for a certain disease has a sensitivity and specificity of 93%. The test is applied to a population of which 11% are actually infected by the disease. 1. Calculate the NPV and the PPV. 2. What percent of the total population will test positive who are disease-free? 3. What percent of the total population will test negative who have the disease?

The most commonly used test for HIV has a sensitivity of 0.997 and a specificity of 0.985. In other words, a person infected with HIV will test positive for the virus 99.7% of the time while a person NOT infected with HIV will test NEGATIVE for the virus 98.5% of the time. Research current rates of infection for the indicated population in order to answer the following questions. If a US randomly selected US resident is tested for HIV and...
