statistical

relating to the use of statistics.

statistics

the practice or science of collecting and analyzing numerical data in large quantities, especially for the purpose of inferring proportions in a whole from those in a representative sample.

The only one with numerical data would be B, because the other answer choices don't give you numerical data meaning it is B because it is the only one that matches the definition of statistical.

For each student in a certain class, a teacher adjusted the student's test score using the formula y = 0.8x + 20, where x is the

alexandr402 [8]

Answer:

Option B) 16

Step-by-step explanation:

We are given the following in the question:

$y = 0.8x + 20$

where x is the student's original test score and y is the student's adjusted test score.

We have to find the standard deviation of the adjusted test scores of the students in the class, if the standard deviation of the original test scores of the students in the class was 20.

We know that:

Adding a constant to each value in a data set does not change the value of the standard deviation.
Multiplying each value in a data set by a constant also multiplies the standard deviation by that constant.

Thus, if we add 20 to each data set then, the standard deviation does not change.

But multiplying each score by 0.8, changes the standard deviation 0.8 times.

Thus, we can write:

$\text{Standard deviation of the adjusted test scores}\\ = \text{Standard deviation of the original test scores of the students}\times 0.8\\= 20\times 0.8\\= 16$

Thus, standard deviation of adjusted score is 16.
