Recently, the ‘‘leap year virus’’ has been spreading over the Internet and infecting the random number generators on many computers. If your computer is infected with this virus, then whenever you attempt to generate a U(0,1) pseudorandom sequence U₁, U₂, U₃, ... the reported value of U_i is forced to be greater than 0.5 (by reporting its ‘‘true value’’ plus 0.5, if necessary) whenever i is divisible by 4, unless it is divisible by 100 but not by 400. Note that the virus only affects the reported values, and does not change the internal state of the generator.

Describe a method for testing your random number generation that will detect this infection. Explain how you would decide whether the random number generator ‘‘passes’’ or ‘‘fails’’ the test. Don’t forget that half the time an uninfected random number generator will also produce a value greater than 0.5 under the same conditions.

a virus is spreading on a small deserted island. The total number of people infected by the virus t days after the outbreak is given by the model p(t)=5200/(1+20^(-t+15)). the different parts can be solved independently. a. How many people will be infected in the long run? (hint: compute the limit of p as t goes too infinity.) b. The island only has a small hospital with a capacity of 250 patients. When will the total number of infections reach...

The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. It is known that the mean number of occurrences in ten minutes is 5.3. The probability that there are 8 occurrences in ten minutes is a. .0771 b. .0241 c. .1126 d. .9107
