Answer:
a. decrease.
Explanation:
If the federal government has a budget surplus in a given year, the national debt will decrease.
If a government has a budget surplus, it implies that the government after carrying out its financial obligations still has extra funds. These extra funds are mostly used by governments to pay off debts thus the national debt will increase. Countries like Belarus, South Korea experience budget surplus.
What we are looking for is the confidence interval.
Given:
Sample it is denoted by n = 10
Mean = 80
Standard deviation = 12
Confidence Interval = 99%
Now compute for the margin of error, the formula is Za/2 * σ/√(n)
A 99% level of confidence has a critical value of zα/2 = 2.58.
The standard error is σ/√(n) = 3.162
Multiply 2.58 by 3.162 = 9.8 is the margin of error.
The formula for confidence interval is x̅ ± Za/2 * σ/√(n)
= 80 ± 9.8
= 70.2 < x< 89.8
Answer: C. aspirin; headaches
Explanation:
The variables in an experiment are either dependent or independent. An independent variable is the change that is introduced to test the hypothesis. A dependent variable on the other hand is the one being monitored or measured due to the introduction of other variables.
Here Headaches are the dependent variables as the experiment is to monitor whether the introduction of aspirin, the independent variable, takes headaches away.
In the "person-situation debate" amongst psychologists, Traits are a false notion. People might not behave consistently in all circumstances, thus it would be beneficial to examine how they respond differently in particular circumstances.
<h3>Which side of the person-situation argument did Mischel take?</h3>
In the psychological community's "person-situation argument," Walter Mischel played a significant role. Character traits are a myth. People might not behave consistently in all circumstances, thus it would be useful to examine the various responses in particular circumstances.
<h3>What exactly is the person-situation argument?</h3>
Nature versus. nurture argument in personality psychology concerns which factor, a person or an environment, is more crucial in predicting what people will do. There is too much variation in behavior across contexts for attributes to adequately describe individual variations.

In 1493, after reports of Columbus’s discoveries had reached them, the Spanish rulers Ferdinand and Isabella enlisted papal support for their claims to the New World in order to inhibit the Portuguese and other possible rival claimants. To accommodate them, the Spanish-born pope Alexander VI issued bulls setting up a line of demarcation from pole to pole 100 leagues (about 320 miles) west of the Cape Verde Islands. Spain was given exclusive rights to all newly discovered and undiscovered lands in the region west of the line. Portuguese expeditions were to keep to the east of the line. Neither power was to occupy any territory already in the hands of a Christian ruler.
No other European powers facing the Atlantic Ocean ever accepted this papal disposition or the subsequent agreement deriving from it. King John II of Portugal was dissatisfied because Portugal’s rights in the New World were insufficiently affirmed, and the Portuguese would not even have sufficient room at sea for their African voyages. Meeting at Tordesillas, in northwestern Spain, Spanish and Portuguese ambassadors reaffirmed the papal division, but the line itself was moved to 370 leagues (1,185 miles) west of the Cape Verde Islands, or about 46°30′ W of Greenwich. Pope Julius II finally sanctioned the change in 1506. The new boundary enabled Portugal to claim the coast of Brazil after its discovery by Pedro Álvares Cabral in 1500. Brazilian exploration and settlement far to the west of the line of demarcation in subsequent centuries laid a firm basis for Brazil’s claims to vast areas of the interior of South America.
