Question

what is the significance of a correlation coefficient of 0.3? (1 point)
the points all lie very close to the line of fit, and the line is decreasing
the points do not follow the line of fit, and the line is decreasing
the points do not follow the line of fit, and the line is increasing
the points all lie very close to the line of fit, and the line is increasing

Explanation:

The correlation coefficient \(r\) measures the strength and direction of a linear relationship. A positive \(r\) (here \(r = 0.3\)) indicates an increasing (positive - sloped) line of fit. The magnitude of \(r\) (0.3 is relatively small) means the points do not lie very close to the line of fit.

Answer:

The points do not follow the line of fit, and the line is increasing.
