Step-by-step explanation:
Population :In statistics, a population is the entire pool from which a statistical sample is drawn.
Sample: A sample refers to a set of observations drawn from a population.

B. 1.55 x 106
Step-by-step explanation:
This is an example of the distributive property. In order to turn it back to the regular form, you need to do this:
3.40
-
1.85
--------
1.55
Don't forget to put the 106!
3.40
-
1.85
--------
1.55 x 106
You can do it in both forms and get the same answer. It depends on what the question asks for or whichever form you like best/you think is the easiest.
