To determine whether they have a certain disease, 100 people are to have their blood tested. however, rather than testing each individual sepa- rately, it has been decided first to place the peo- ple into groups of 10. the blood samples of the 10 people in each group will be pooled and ana- lyzed together. if the test is negative, one test will suffice for the 10 people, whereas if the test is posi- tive, each of the 10 people will also be individually tested and, in all, 11 tests will be made on this group. assume that the probability that a person has the disease is, p= 0.1 for all people, independently of each other, and compute the expected number of tests necessary for each group. (note that we are assuming that the pooled test will be positive if at least one person in the pool has the disease.)
