B) descriptive and inferential statistic

Explanation:

Statistics is a tool that works to get information from data. This can happen in two different ways, inferential statistics and descriptive statistics.

Descriptive statistics involves the organization, summary and representation of data. The tools used for this are the frequency tables; graphics; calculation of central tendency measures such as mean, median and fashion; and calculation of variation measures such as variance and standard deviation.  In inferential statistics, we seek to obtain information from a data grouping through a sample of these data. In this sense, a widely used tool in inferential statistics is probability.

explanation:

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
