# Long description

In the population distribution for normal, a bowed-outward parabolic curve is seen on a plane. In the population distribution for Beta, a bowed-outward curve that is skewed toward the left is seen on a plane. In the population distribution for uniform, a rectangular box-shaped curve is seen on a plane. Each of the distribution has Mu as the mean and Sigma sub x as the standard deviation.

In the sampling distribution of an always normal sample means:

A plane has the values -3 sigma sub x bar, -2 sigma sub x bar, -1 sigma sub x bar, Mu x bar equals Mu, 1 sigma sub x bar, 2 sigma sub x bar, and 3 sigma sub x bar.

A bowed-outward parabolic curve is seen over this plane.

A bidirectional dotted line in the curve from one-third distance ...
