4. Generalize the Bayesian analysis of medical screening given in class. Let a rare disease D occur with probability P(D) = δ, with δ small. The test for this disease is accurate such that the probability of a correct result is 1-e, with e small. Derive formulas for the probabilities of a true positive P(D|+) and a false positive, P(D'l+). For this screening to be useful at a given δ, what is required of e ?

4. Generalize the Bayesian analysis of medical screening given in class. Let a rare disease D occur with probability P(D)-δ, with δ small. The test for this disease is accurate such that the W1 probability of a correct result is 1-e, with ε small. Derive formulas for the probabilities of a true positive P(D +) and a false positive, P(p+). For this screening to be useful...

Just need part c and d
11. The screening process for detecting a rare disease is not perfect. Researchers have developed a blood test that is considered fairly reliable. It gives a positive reaction in 98% of the people who have that disease. However, it erroneously gives a positive reaction in 3% of the people who do not have the disease. Consider the null hypothesis "the individual does not have the disease" to answer the following questions. a. What is...

Medical screening tests are used to check for the presence on disease, evidence of illegal drug use, etc. The its sensitivity and its specificity. The sensitivity among those with the condition that will test positive. The specichy proportion among those without the condition that will test neg sensitivity of a test is defined to be the conditional ng those without the condition that will test negative. More formally, the test is defined to be the conditional probability that a person...

A bag contains 4 red and 5 green balls. Let X denotes number
of red and Y denotes number of green balls in 2 drawn from the bag
by random. Find joint probability distribution, compute E(x), E(Y)
and correlation coefficient. 2. A diagnostic test has a probability
0.95 of giving a positive result when applied to a person suffering
from a certain disease, and a probability0.10 of giving a (false)
positive when applied to a non-sufferer. It is estimated that...

3. Let C be the event that a patient suffers from a certain condition, and let T denote a positive result from a lab test that is designed to detect the presence of said condi- tion. Suppose that the proportion of the population that actually has the condition IS E E (0,1). Additionally, suppose that, when the condition is actually present in a patient, the test is positive with probability a (0,1). On the other hand, when the patient does...

It is understood that in number 4, the blood types do
not add up to 1.0 and that is fine.
Problem #1 (8 points) Suppose you have gone bowling with an excellent player who bowls a strike (ie when they hit all of the pins) 73% of the time. By the fourth frame, this person realizes that they can clincha first place in a local tournament by bowling 3 consecutive strikes. What is the likelihood of this happening! Problem #2:...
