In civil war history (june 2009), historian jane flaherty researched the condition of the u. s. treasury on the eve of the civil war in 1861. between 1854 and 1857 (under president franklin pierce), the annual surplus/deficit was plus18.8, plus6.7, plus5.3, and plus1.3 million dollars, respectively. in contrast, between 1858 and 1861 (under president james buchanan), the annual surplus/deficit was minus27.3, minus16.2, minus7.2, and minus25.2 million dollars, respectively. flaherty used these data to aid in portraying the exhausted condition of the u. s. treasury when abraham lincoln took office in 1861. does this study represent a descriptive or inferential statistical study? explain.

Statistics are divided into two main branches: the descriptive one that, as the name implies, seeks to describe the data through mathematical processes that allow them to be analyzed, find numerical patterns, representative data, group values and summarize the information; the other branch is the inferential, which seeks to make estimates or predictions, inferences, on a set of data obtained, usually samples, making use of probabilities and distributions.

Answer

The study described is a descriptive study since it performs a series of mathematical processes on a set of data to be able to analyze them, find representative patterns and data, describe their behavior and make a comparison.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
