Are all symmetric distributions normal distributions?
No. There are many other distributions, including discrete ones, that are symmetrical.
The usual sampling distributionof the difference between means is a what?
There is no such thing as "the usual sampling distribution". Different distributions of the original random variables will give different distributions for the difference between their means.There is no such thing as "the usual sampling distribution".

Is the beta distribution is a special case of dirichlet distribution?
In a sense.Beta distributions are the marginal distributions of the Dirichlet distribution.
Do normal probability distributions have different arithmetic means and different standard deviations?
Yes. And that is true of most probability distributions.
What is the formula to calculate pitch of a hexagonal nut?
For metric, use mm - For English, use Inches English Example: [ 1inch / (thickness of nut) ] x (number of turns for the bolt to get through the nut ) typical numbers are 18, 24, and 32. Metric: (thickness of nut in mm) / (number of turns for the bolt to get through the nut) typical numbers are 1, 1.25, 1.5, and 2.
How do you find the mean of frequency distributions?
For discrete distributions, suppose the variable X takes the specific value x with probability P(X=x) Then add together x * P(X = x) for all possible values of x. For continuous distributions, suppose the probability distribution function of the variable X is f(x). Then the mean is the integral of x*f(x) with respect to x, taken over all possible values of x.

What is the range of skewness of approximately symmetric distributions?
-1<x<+1
Why you prefer normal distribution over other distribution in statistics?

Are all symmetric distributions normal distributions?
No. There are many other distributions, including discrete ones, that are symmetrical.
Does the rain shadow effect cause rain to fall in equal distributions over all areas?
NO
Why does nut arch over geb?
Geb is the god of the earth; Nut is the goddess of the sky.
What when there in no mode?

Are IRA distributions taxable?
It depends on the type of IRA you have. Distributions from a traditional IRA are taxable. Distributions from a Roth IRA are not taxable.
What is the formula to determine the standard deviation of the resulting normal distribution when adding two normal distributions with different means and standard deviations?
s= bracket n over sigma i (xi-x-)^2 all over n-1 closed bracket ^ 1/2
