These are the options for the question:

A. -4.57

B. -.47

C. +.91

D. +0.00

The correct answer is:

B. -.47

Explanation:

The Pearson Correlation Coefficient measures the linear correlation between two variables. The value of the coefficient goes form +1, which indicates a perfect positive correlation, to 0, which indicates neutrality or no correlation, to -1, which indiciates a perfect negative correlation.

The question is telling us that the more alcohol a person consumes, the poorer his performance on the test. That means that if one variable goes up (alcohol consumption), the other goes down (performance on the test), therefore, we see a negative correlation. We do not know how strong the negative correlation is, but we know for sure that it is negative.

And the only value among the options for the question that is valid is B) -.47.

While -4.57 is also a negative value, this option is incorrect because the correlation coefficient cannot be less than -1.

facts: the 14th amendment

the 14th amendment addresses citizenship rights and equal protection of the laws.

the 14th amendment was intended to protect the rights of former slaves after the american civil war.

the 14th amendment was approved by congress in june of 1866 and ratified by the states on july 9, 1868.

the 14th amendment establishes that all persons born in the united states are citizens and are guaranteed all the rights of citizenship.

the 14th amendment establishes that the law protects all citizens equally.

in this case the passage of the 14th amendment that was violated was the last part in which it states that there is equal protection of the law.
