A particular hypothetical human disease occurs with a probability of 0.1 in males and with a probability of 0.4 in females.

(a) Assuming that the frequency of males is 0.5 and females 0.5 in a very large population, what is the probability that an individual selected at random from this population will have the disease?

(b) What is the probability that a random individual will be male given that this person has the disease?

Suppose that the probability of having a particular disease is 0.05. Suppose that the probability of testing positive for the disease is 0.95 given that a person has the disease and 0.04 given that the person does not have the disease. Given that a person tests positive for the disease, what is the probability that they actually have the disease? (Answer to four decimal places).

A small town has 7000 adult males and 5000 adult females. A sociologist conducted a survey and found that 40% of the males and 30% of the females drink heavily. An adult is selected at random from the town. (Enter your probabilities as fractions.) (a) What is the probability the person is a male? (b) What is the probability the person drinks heavily?

The probability that an individual randomly selected from a particular population has a certain disease is 0.06. A diagnostic test correctly detects the presence of the disease 92% of the time and correctly detects the absence of the disease 93% of the time. If the test is applied twice, the two test results are independent, and both are positive, what is the (posterior) probability that the selected individual has the disease?

1) Let D = 1 denote the event that an adult male has a particular disease. In the population, it is known that the probability of having this disease is 20 percent, i.e.,Pr(D = 1) = :2 Now, suppose that an adult male has a son. Unlike the father's birth, new health policy now requires that all newborn males are tested for the disease. Suppose that a particular adult male's son is tested, and is confirmed not to carry this...

It is known that, on average, one hundred people (1 in 100) have a particular disease. A diagnostic test is devised to screen for this disease. A positive result is one that suggests that the person has the disease, and a negative result is one that suggests that the person does not have the disease. The possibility of errors in the test gives the following result probabilities: For a person who has the disease, the probability of a positive result...

A hypothetical form of dwarfism inherited in an autosomal dominant fashion. Males and females are affected equally. Individuals carrying the allele have shortened appendages with normal size torso and head. Individuals carrying two copies of the allele die. The disorder is carried by less than 5% of the population. a. Determine the genotype for the majority of the population. b. Two normal individuals can have a child expressing this disorder. What does this indicate about the origin of most cases...

Suppose that a rare disease occurs in the general population in only one of every 10,000 people. A medical test is used to detect the disease. If a person has the disease, the probability that the test result is positive is 0.99. If a person does not have the disease, the probability that the test result is positive is 0.02. Given that a person’s test result is positive, find the probability that this person truly has the rare disease?
