Answer:

The Answer is below

Step-by-step explanation:

The correlation coefficient for the linear regression of the data is a mathematical illustration, that describes the level of correlation in linear relationship between the two variables and the direction, which can either be positive or negative.

Give the sign of "r" depicts the direction of the relationship. Thus, if "r" is positive, as one variable increases, the other tends to increase, and if "r" is negative, as one variable increases, the other tends to decrease.

As such, r² is represented as the proportion of the total variance (s²) of Y, which in turn can be expressed by the linear regression of Y on x. Thus, 1-r² is the part that is not illustrated by the regression.

A pair of congruent triangles will have the same three side lengths and the same the angles. The equal sides and angles may not be in the same position due to turning or flipping, but they are always there. You can draw a phone with congruent lines on each triangle.

You order them least to greatest, then take out your mean, median, and mode. Then you've got your outliners left over.
