Answer:

A. simpson's paradox

Step-by-step explanation:

The Simpson's paradox was named after Edward Simpson, the person who described this paradox for the first time in 1951. In this paradox, you find two contrary patterns. For example, a positive and a negative correlation, depending on how data is analyzed. The differences in the analyses are how data are grouped. This paradox is observed often in social researches. Most of the times, results are affected by the sample on each group or additional information related to the data.

Point v is graphed on a number line at -6...point u is 8 units away from v....notice that it doesn't say which way....so it can go either way....so we need to find 8 units away from -6 in both directions

-6 + 8 = 2
-6 - 8 = -14

so point u can be either at 2 or at -14...ur answers are A and D

Gekata [30.6K]

Answer:

A) The applicant's SAT z-score has to be positive and large.

Step-by-step explanation:

The zscore measures how much above or below the mean a value is in a normally distributed sample. The value can be a grade, for example.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by

Z = \frac{X - \mu}{\sigma}.

When the zscore of X is negative and large, this means that the grade is on the very low side(very below the mean).

When the zscore of X is negative and small, this means that the grade is on the low side(a bit below the mean).

When the zscore of X is close to 0, the grade is close to the mean.

When the zscore of X is positive and small, this means that the grade is on the high side(a bit above the mean).

When the zscore of X is positive and large(Z > 1), this means that the test score is on a very high side.

The problem states that:

To get admitted to top universities, the applicant's SAT (Scholastic Aptitude Test) score must be on a very high side. So, the correct answer is:

A) The applicant's SAT z-score has to be positive and large.
