Given that a certain medical condition is found in 1 out of 1000 persons. For an island with a population of 500, the distribution ?~?(500,0.001) could be used to describe the proportion of population that is infected with the condition. (d) Assuming the above Binomial proportion is applicable for another island with a population of 5000, and by using an appropriate approximation, find: (i) the expected number of persons with the condition (ii) the probability that there will be more...

A medical test is not completely accurate. When people who have a certain disease are tested, 90% of them have a "positive" reaction. But 5% of people without the disease also have a "positive" reaction. In a certain city, 20% of the population have the disease. A person from this city is chosen at random and tested; if the reaction is "positive," what is the probability the person has the disease

Consider a small town that has a population of 1,000 people. It is known that in this town, 10 people are infected with a rare disease. The remaining 990 people are NOT infected with the disease. This data is known with certainty. Recently, The FDA (Food and Drug administration) developed a test that determines if a person is infected with this disease. However, as with most test of this nature, it is not foolproof proof as there are a certain...

Voting records in a certain state show that 53% of those registered to vote are Democrats.

The reporters are working independently, so it is possible (but unlikely) that some voter is chosen by more than one of the reporters. What is the probability that at most 6 of the 9 reporters choose...

1. A certain town has 10,000 Occupied rental units. A local real estate office does a survey of these units: 250 are chosen at random, and the occupants are interviewed about their rent paid in the previous month. The 250 sample rents have an average of $168. Assume the standard deviation of rent in this town is known to be $300 and that rents in this town are normally distributed. Find a 95% confidence interval for the average rent paid...
