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.

Answer 1

9 points

Explanation:

Answer 2

Answer: 9 points

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
`R ^ 2 = 1` means that the model explains the entire variation between the two variables without error.

Therefore, in this case if
`R ^ 2 =1` means that the 9 points are on the line
