72. Which of the following is NOT TRUE about the theoretical distribution of sums?

a. The mean, median and mode are equal.

b. The area under the curve is one.

c. The curve never touches the x-axis.

d. The curve is skewed to the right.

Short answer

d. The curve skewed to the right is not true.

Step-by-step solution

Given Information

Frequently in measurements, we will generally address a bunch of information by delegate esteem which would roughly characterize the whole assortment. This delegate esteem is known as the proportion of focal propensity, and the name proposes that it is a worth around which the information is focused. These focal propensities are mean, median and mode.

Explanation 

The central limit theorem states that as far as possible hypothesis spreads out free sporadic elements are summed up, their properly normalized complete slopes toward a run of the mill course whether or not the principal factors themselves are not consistently conveyed.

Hence the curve skewed to the right is not true.
