In a particular region, the probability that a randomly chosen individual is a smoker is 0.32. A sample of 25 people is chosen from the region, and we define Xi=1 if the i−th person is a non-smoker and Xi=0 if the i−th person is smoker. What is the distribution of of X1+X2+...+X25. ?

In a given population, n individuals are sampled randomly, with replacement, and each sampled individual is asked whether his/her salary is greater than some fixed threshold z. Assume that the salary of a randomly chosen individual has the exponential distribution with unknown parameter λ. Asking whether the salary overcomes a given threshold rather than directly asking for the salary increases the number of people that are willing to answer and decreases the number of mistakes in the collected answers. Denote...

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?
