Question

If the coefficient of determination for a data set containing 9 points is 1, how

many of the data points must lie on the regression line for the data set?
O A. 9
OB. 8
O C. 6
O D. 7

Answer 1

Therefore, in this case, it means that the 9 points are on the line

Explanation:

Answer 2

Answer: A

Explanation:

The coefficient of determination is a number between 0 and 1 used to measure the level of precision with which the regression model created fits the data. A measure of means that the model explains the entire variation between the two variables without error.

Therefore, in this case, if means that the 9 points are on the line
