13. What does a correlation coefficient of r = - 0.97 generally imply about the graph of a data set? *1 pointA) The slope is positive, and a linear model is a good fit for the data.B) The slope is negative, and a linear model is a good fit for the data.C) The slope is positive, and a linear model is NOT a good fit for the data.D) The slope is negative, and a linear model is NOT a good fit for the data.
Accepted Solution
A:
The answer is B. The closer the r value is to 1 or -1, the better the fit is. If the r value is negative, the slope is negative. If the r value is positive, the slope is positive.
