- A food scientist is testing chicken samples to determine
whether they are infected with salmonella. Suppose that she has a 5
batches, 2 of which are infected with salmonella. She randomly
selects two of the batches and tests them for the bacteria. Let W
denote the number of batches, out of the two tested, that are
infected with salmonella.
- Find the probability mass function for W.
- What is the probability that both batches are infected?
- What is the expected number of infected batches?

RBV testing Suppose that 1% of all people are infected with the rare banana virus (RBV). There is a test to detect the RBV: if you do have the RBV, then the test will correctly detect this 99% of the time; if you do not have RBV, then the test will correctly indicate this 97% of the time. We assume that if the RBV test is given repeatedly to the same person, then the test results are independent of cach...

To determine whether or not they have a certain disease, 80 people are to have their blood tested. However, rather than testing each individual separately, it has been decided first to group the people in groups of 10. The blood samples of the 10 people in each group will be pooled and analyzed together. If the test is negative. one test will suffice for the 10 people (we are assuming that the pooled test will be positive if and only...

Suppose a shipment of 130 electronic components contains 3 defective components. To determine whether the shipment should be accepted, a quality-control engineer randomly selects 3 of the components and tests them. If 1 or more of the components is defective, the shipment is rejected. What is the probability that the shipment is rejected?

a) An industrial product is shipped in lots of 15 items. Testing to determine whether an item is defective is costly, and hence the manufacturer samples his production rather than inspecting each item. A sampling plan is devised and calls for sampling five items from each lot. If the lot contains four defectives, what is the probability that exactly two defectives are found in this sample? b) You run into your long lost relative at the airport, but you have...

Determine whether the conditions for the binomial distribution are satisfied. If the conditions are not satisfied, state why not. A polling agency in one city randomly selects 1000 registered voters from a pool of 385,600 registered voters of whom 17% are African American. Let X be the number of African Americans in the sample. A. The conditions for binomial distribution are not satisfied. The probability of success is not the same on each trial. B. The conditions for binomial distribution...

Viewers were asked to call one telephone number to respond “Yes” and the other to respond “No”. More than 186,000 callers responded and 67% said “No.” This isan example ofA. voluntary response sampling.B. a survey with little bias because a large SRS was used.C. a survey with little bias since someone who called would...

A quality-control engineer wants to find out whether or not a new machine that fills bottles with liquid has less variability than the machine currently in use. The engineer calibrates each machine to fill bottles with 16 ounces of a liquid. After running each machine for 5 hours, she randomly selects 15 filled bottles from each machine and measures the volume of their contents (in ounces). The resulting data is provided in the table below. Is the variability in the...
