Question

how can you use random samples to solve real - world problems? you can use random samples to obtain a (select) representation of populations that are too large to survey. (select) small true biased

Explanation:

To fill in the blank, we analyze the context. The sentence is about using random samples to get a certain type of representation of large populations for a survey. A "true" representation makes sense here because random sampling aims to get an accurate (true) depiction of the population, avoiding bias. "Small" doesn't fit as the population is too large, and "biased" is the opposite of what random sampling aims for.

Answer:

true
