Problem A diagnostic test has a probability 98% of giving a positive
... Problem We roll a fair die with 8 faces. The faces are labeled by distict letters. What is the probability that the same letter (no matter which) occurs 3 times in 5 rolls ? Give the probability in percentage with 2 decimal digits. Solution The probability that a given letter occurs k = 3 times in ...

... Example: A classic example of the Poisson distribution involves the number of deaths caused by horse kicks in the Prussian Army between 1875 and 1894. During that 20 year period there were 196 deaths by horse kick. That’s an average of 196/20 = 9.8 horse-kick deaths per year in the Prussian Army. Re ...

Some Remarks on Rao and Lovric`s `Testing Point Null Hypothesis
... which a rejection implies a meaningful result. One tests against a negligibly small or trivial effect. If one rejects the null range hypothesis this implies not only that, for example, the mean of the experimental group is different than control group, but the difference is of large enough magnitude ...

... together, and for each one of those choices there are 42 = 6 ways to choose the two bowls to place the other two oranges with one orange per bowl. So, there are 5(6) = 30 ways for this scenario to occur. This gives a total of 5 + 10 + 30 = 45 ways. (b) Suppose that five men and five women are invite ...

Shannon`s Noisy Coding Theorem 1 Channel
... showing that if we want to transmit a message error-free using blocks of n bits, we must have log M = Rn ≤ n(1 − H(p) + δ′′ ). Thus, if we transmit bits at a rate R ≥ 1 − H(p), for long enough messages we will inevitably introduce errors. We will next show that we can indeed find a coding scheme whi ...
