Match each concept with its key characteristic. 1. subset of a group survey 2. equally favors all members of a group sample mean 3. collects data on members of a group population 4. does not equally favor all members of a group random sample 5. includes all members of a group sample 6. analyzes data collected from a group biased sample

1. It is the subset of a group  - Group sample.

2. It equally favors all members of a group sample   - Random sample.

3. It collects data on members of a group  -  Survey.

4. It does not equally favor all members of a group - Biased sample.

5. It includes all members of a group   -  Population.

6. It analyzes data collected from a group - Mean.

I have matched all concepts in accordance with statistical use, hope it helps.

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
