Calculate the range, population variance, and population standard deviation for the following data set. If necessary, round to one more decimal place than the largest number of decimal places given in the data. 16,12,17,8,15,15,10,11,19,18

Step-by-step explanation:

Given

Solving (a): Range

This is calculated as:

Where:

So:

Solving (b): The population variance

First, calculate the population mean using:

So:

So, the population variance is:

--- approximated

Solving (c): The population standard deviation.

This is calculated as:

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

answer: idk
