For an experiment looking at how many mice in a population carry a certain disease, what would a positive control be?
Homework Answers
There are found two controls in an experiment the first one is positive control and the second one is negative control. In negative control, we have to design in such a way that we will not get any result but in a positive control we will design our control in such a way that we get our expected results.
We have to take the mice which have disease as the positive control because in positive control we have to setup in such a way that there is found the the expected result it is found in our experiment which we want to perform.
Now we compare the the mice which have disease with our positive controls samples. The mice which are found to be the same as found in positive control. These mice counted as a disease mic. e

ltis known that 3% ofthe Uk's population carry a certain disease. Atest forthe disease is available Leave 5 which always gives either a positive or a negative result. Given that the individual carries the disease, there is a 98% chance that the test will give a positive result. Given that the individual does not carry the disease, there is a 95% chance that the test will give a negative result. blank a) i) Joey takes the test and gets a...

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...

It is known that 2.6% of the population has a certain disease. A new test is developed to screen for the disease. A study has shown that the test returns a positive result for 18% of all individuals, and returns a positive result for 92% of individuals who do have the disease. If a person tests positively for the disease under this test, what is the probability that they actually have the disease? 0.1276 0.1329 0.1435 0.1223 O 0.1382

One percent of all individuals in a certain population are carriers of a particular disease. A diagnostic test for this disease has a 95% detection rate for carriers and a 4% detection rate for non-carriers. Suppose the test for this is applied independently to two different blood samples from the same randomly selected individual. Hint: Use Notation A= {no disease} A'={disease} B1= {1st test positive} B2={2nd test positive} a) What is the probability that the first test is positive? b)...

It’s known that 2 % of people in a certain population have the disease. A blood test gives a positive result (indicating the presence of disease) for 95% of people who have the disease, and it is also positive for 3% of healthy people. One person is tested and the test gives positive result. a. If the test result is positive for the person, then the probability that this person actually has a disease is _________ b. If the test...

I have two different strains of mice being tested for the incubation period of a certain disease. the test is comparing two different strains in terms of length of the incubation period. I need to know how many populations are involved in test 2 or 1?why?

In a laboratory setting, scientists are testing the claim that a certain contagious disease spreads at a rate that is proportional to the number of interactions between those that are infected x(t) and those that are disease-free y(t). To do this, the scientists begin with a population of 500 mice. Ten of the mice are removed, infected with the contagious disease, and then returned to the rest of the population. 1. Find a mathematical model that estimates the number of...

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.

The probability that an individual randomly selected from a particular population has a certain disease is 0.04. A diagnostic test correctly detects the presence of the disease 94% of the time and correctly detects the absence of the disease 96% 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?
