A major approach to "confirming what the data reveal" is the calculation of

D. confidence intervals for a population parameter.

Explanation:

Standard deviation is simply a measure of the amount of dispersion of a set of values from the mean, hence it is not used to confirm what the data reveal.

Stem-and-leaf plots simply shows the frequency with which a set of values occur and hence it is not used to confirm what the data reveal.

A measure of central tendency, also sometimes signifies mean, mode, and median simply represents the typical value or middle point of a set of data, and hence it is not used to confirm what the data reveal

Confidence intervals for a population parameter refers to the probability of population parameter falling between two set values for a certain proportion of times. With the presence of probability, this shows that it is used to confirm what the data reveals.

the aksumite empire was an ancient kingdom located in what is now northern ethiopia from the period of 100 ad to 940 ad. its capital was the city of aksum. the kingdom established itself as one of the 4 great powers at its time, along with persia, rome, and china.

the kingdom was rich in goods like gold, iron, and salt. it established strong commercial ties with the regions governed by rome, egypt, and persia (arabia). aksum was a key location in this commercial network. trade was also facilitated with the introduction of the aksumite currency.
