Answer: unreliability

Explanation: Some of the problems that determine the quality of an experiment are reliability and validity.  

Reliability considers the consistency of the experiment. In the example above,  the result of the second sample is inconsistent with the result of the first sample, making Watt's research unreliable. That is, it does not reflect the ratings of a larger population. This problem can be solved by increasing the sample size, such that the average ratings are more reflective of a wider audience.

Validity considers the accuracy of the experiment. A lack of reliability of an experiment will likely make the result invalid as well, but this is not always the case.

Explanation:

Kush earned a lot of money when they were trading (especially iron) in their capital of Meroe because it was strategically placed. When they stopped trading iron because of the shortage of wood to burn to smelt iron, their trading came to a halt. This combined with people from Axum attacking Kush caused Kush to fall. Axum benefited from the great trade location by a lot. Greco-Roman traders would come and offer many important goods.

If Debra turns down the full-time position at Burger Hut, what is the most reasonable economic explanation for her decision?
olga2289 [7]

The most likely reason for any person turning down a full-time job is money.

It is more likely than not that Burger Hut was unable to provide compensation for Debra's services at a rate that a. Debra felt appropriate or b. Debra felt was necessary to make accepting the job worthwhile.

For instance, if Debra lived far away from the Burger Hut than any job would need to pay enough to partially cover the cost of her commute in addition to living and (hopefully) saving money.
