... 4-4.4 Large-Sample Test In general, if n 30, the sample variance s2 will be close to 2 for most samples, and so s can be substituted for in the test procedures with little harmful effect. That is for large sample sizes: X approx N 0,1 S n ...

... Definition: Let E and F be events with p(F) > 0. The conditional probability of E given F, denoted by P(E|F), is defined as: Example: A bit string of length four is generated at random so that each of the 16 bit strings of length 4 is equally likely. What is the probability that it contains at least ...

... Careful with the MEAN and MEDIAN So should we be focusing on the median more than the mean???? No. Generally speaking, the mean is TYPICALLY a far more accurate measurement in terms of central tendency than the median when outliers have been dealt with. To convince yourself, try this exercise from S ...

... is solved in the following two steps: 1) find y0 such that exp(-y0)(1+y0)=p and 2) compute t by t:=y0/n. In the end of this section we deal with estimated cumulative distribution functions. Some methods to obtain density estimates based on sample data are known in literature (Silverman 1986). The d ...
