Suppose it is known that the probability of being susceptible to contract a seasonal flu disease in a town is 0.20. A bio-statistician randomly selected 12 unrelated people from the town and examined if they are susceptible to the disease. Considering upto 4 decimal places, find the following: (a) expected number of susceptible individuals; (b) probability that 2 or fewer susceptible individuals; (c) probability that exactly 3 susceptible individuals; (d) probability that at least 4 susceptible individuals.

Suppose that a community contains 15,000 people who are susceptible to a contagious disease. If N(t) represents the number of people who have become infected in thousands, where t is time in days, and N′(t) is proportional to the product of the numbers of those who have caught the disease and of those who have not. The following logistic model can be used to model the spread of the disease. dN/dt= 1N(15−N) dt 100 (a) Sketch the phase line (portrait)...

Suppose there is a 5% probability (or risk) that you will get a very severe flu next year. If you get the flu, you will be admitted to the Hospital for at least a week, and in turn you will need to pay $2,000 for a hospital service and medical expenses. Keep in mind that you are risk-averse. While you can’t avoid getting the flu, you can avoid a financial loss due to the flu by buying a health insurance....

When testing for a disease such as the flu, there is always the possibility of receiving a false negative (meaning that you have the disease but tested negative) and a false positive (meaning that you do not have the disease but tested positive). Last month, a collection of people at a clinic were tested for the flu. After the results were confirmed after medication, here were the results. Tested Positive Tested Negative Had Disease 816 26 Didn’t Have Disease 31...

Suppose that at the beginning of March, a new strain of flu, flu-A, emerges and begins to spread through U-College undergraduates. The symptoms of Flu-A are like the common flu, flu-B, and other respiratory illnesses. It is thought that the infection rate of Flu-A will be similar to that of Flu-A at other colleges, but that the disease will be much less deadly. Flu-A is expected to infect about 20 out of every 1,000 undergraduate students per month for the...
