Why do we Sample instead of looking at the entire population if we understand that a Sample is not the true representative of the population? a. Sample results are adequate and therefore enough to make a population inference. b. It is physically impossible to check the entire population most of the time. c. Studying the whole population may be too time consuming d. The Cost of studying the entire population may be prohibited e. All of the reasons are correct.

e. All of the reasons are correct.

Step-by-step explanation:

In most cases, studying all the population is impossible. In other cases, it is too expensive or time consuming.

A sample will give us, in most cases and combined with tools of statistical analysis (hypothesis testing or confidence intervals), enough information to make an unbiased estimation about the characteristic of the population we are studying.
