QUESTION 7

a. Approx. 7.0296
b. Approx. 92.98%
c. Approx. 98.72%
d. None of the above
QUESTION 8
In a clinical study, volunteers are tested for a gene that has been found to increase the risk for a disease. The probability that a person carries the gene is 0.1. What is the probability that the 6th individual test is the FIRST person with the gene in question?
a. Approx. 7.0296
b. Approx. 92.98%
c. Approx. 98.72%
d. None of the above
#7.
p = 0.1
P(X >= 3) = 1 - P(X <3)
= 1 - P(X = 0) - P(X = 1) - P(X = 2)
= 1 - (1 - 0.1)^10 - 10C1*0.1*0.9^9 - 10C2*0.1^2*0.9^8
= 1 - 0.9298
= 0.0702
approx. 7.02%
#8.
Required probability = 0.9^5*0.1 = 0.0590

In a clinical study, volunteers are tested for a gene that has been found to increase the risk for a disease
In a clinical study, volunteers are tested for a gene that has been found to increase the risk for a disease. The probability that a person carries the gene (independently of other people) is 0.1. What is the probability that we will have to test at least 7 people in order to find 4 people who carry the gene?(a) .9982 (b) .00255 (c) .9987 (d) 1.458×10-6 (e) .00346

1) Clinical studies of 1000 people were analyzed to determine if they have a gene that predisposes people to have skin cancer. That study revealed that the probability that a person has the gene predisposed to contract cancer is 0.1. a) Calculate the probability that 4 or more people have to be analyzed before two people are detected with the gene. bi on average, how many people must be analyzed for 2 people to be detected? with the gene.
A rare but serious disease, D, has been found in 0.01 percent of a certain population. A test has been developed that will be positive, p, for 98 percent of those who have the disease and be positive for 3 percent of those who do not have the disease. Find the probability that a person tested as positive does not have the disease.
annuais 8. A group of volunteers for a clinical trial consists of 81 women and 98 men. 31 of the women and 27 of the men have high blood pressure. If one of the volunteers is selected at random, find the probability that the person has high blood pressure given the person is a man. A) 27/98 B) 31/81 C) 31/58 D) 27/98 E) None of the Above 0.000

It has been found that 0.01% of the world population has a certain disease. If a person has the disease, there is a 95% chance they will test positive for the disease. If a person does not have the disease, there is a 5% chance they will test positive for the disease. (a) What is the probability that a person chosen at random will both have the disease and test positive? 0.000095 (or 9.5 x 10-5) (b) What is the...
A medical test has been designed to detect the presence of a certain disease. Among people who have the disease, the probability that the disease will be detected by the test is 0.94. However, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.05. It is estimated that 6% of the population who take this test have the disease. (Round your answers to three decimal places.) (a)...
A new medical test has been designed to detect the presence of the mysterious Brainlesserian disease. Among those who have the disease, the probability that the disease will be detected by the new test is 0.820.82. However, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.020.02. It is estimated that 14%14% of the population who take this test have the disease. Let DD be the event...
