Coby analyzes a data set and finds that r = 0.88. what is the coefficient of determination for his data set?

Step-by-step explanation:

r represents the correlation coefficient between two sets of data. It is a measure of the degree of association between the two sets of data and gives insight into the strength and direction of the relationship.

On the other hand, is the coefficient of determination for a given data set. It is a measure of the predictive power of a linear model.

Given r, is simply the square of r;

in this case we are given, r = 0.88. Therefore,

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
