The coefficient of determination of a set of data points is 0.862 and the slope of the regression line is - 3.27. Determine the linear correlation coefficient of the data. What is the linear correlation coefficient? r= (Round to three decimal places as needed.)

You generate a scatter plot using Excel. You then have Excel plot the trend line and report the equation and the r2r2 value. The regression equation is reported asy=−99.98x+51.42y=-99.98x+51.42and the r2=0.2704r2=0.2704.What is the correlation coefficient for this data set?r =

You generate a scatter plot using Minitab. You then have Minitab plot the regression line and report the equation and the r2 value. The regression equation is reported as y=43.41x+77.98 and  the r2=0.2025.What is the correlation coefficient for this data set? r =

For a data set of brain volumes (cm°) and IQ scores of six males, the linear correlation coefficient is r= 0.647. Use the table available below to find the critical values of r. Based on a comparison of the linear correlation coefficient r a values, what do you conclude about a linear correlation? Click the icon to view the table of critical values of r.
