What is the probability that x will take on a value between 21 and 25? X is a continuous uniform (-5, 5) random variable. (a) What is the PDF f_X(x)? (b) What is the CDF F_X (x)? (c) What is E[X]? (d) What is E[X...
The first quartile is the same as the 25th percentile of a dataset. 3 Quantile In statistics and probability, quantiles are cut points dividing the range of a probability distribution into continuous intervals with equal probabilities, or dividing the observations in a sample in the same way. The...
I'm looking for a probability distribution function (and CDF) for which the mean is undefined, but not symmetric like Cauchy, but a positive, continuous probability distribution with infinite mean and with a maximum density away from zero -- shaped like Poisson with a "hump". I think ...
