... both above (or both below) the median is 25%.. This comes from the multiplication rule: If A is the probability that the first number is above the median, and B is the probability that the second number is above the median, then P A B P A PB if A and B are independent events. If the pr ...

... the Margins data, the resulting «-, has mean /a, = (s + 1 + k)/(n + 2 + 2k) and standard deviation oti = llr\/n + 2k (in the large-/: approximation, which is clearly justified), as can be seen from the functional form of £ and the fact that multiplying by w0 is equivalent to the substitution s — s + ...

Note
... Each value is a realization of what is known as a continuous random variable. One assumption we may make is that there is no trend with time. The values change from day to day in a way which we cannot predict – again we need to find a model for the downloading time. For example we assume that the do ...

... 2+2+1+1, 2+1+1+1+1, and 1+1+1+1+1+1. So, the probability that he at some point sums to 6 will be equal to the sum of the probability of rolling each of these sequences, times the number of ways it can be accomplished. Here, C(n,r) refers to the combination function, n!/[r! * (n-r)!]. The probability ...
