To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.
You integrate the probability distribution function to get the cumulative distribution function (cdf). Then find the value of the random variable for which cdf = 0.5.
say you have 3,45,5 you do 3+45+5 then divide it by 3 because there is 3 numbers
You find the event space for the random variable that is the required sum and then calculate the probabilities of each favourable outcome. In the simplest case it is a convolution of the probability distribution functions.

a = ±2.12, depending on the inequality for Z.

If you don't initialize it, you will find random garbage in it. (The same is true for auto class.)
Prob (-1.31 < z < 0.31) = 0.5266
X is a variable. So you subtract 7 minus 2 to find the variable answer.So your answer is 5
if you want to find out an answer to a variable go google and type in Variable Calculator, oh yeah and um, b=37...
