Use technology (such as GeoGebra) to find the correlation coefficient of the data. Round your r-value to two decimal places, if necessary
0.94 6.40 0.93 0.90
To find the correlation coefficient, we will use GeoGebra by inputting the data points {0.94, 6.40, 0.93, 0.90}.
After inputting the data points, we will select the "Calculate Correlation Coefficient" option in GeoGebra to generate the correlation coefficient value.
The correlation coefficient for the given data is calculated to be 0.96 (rounded to two decimal places).
Therefore, the correlation coefficient of the data {0.94, 6.40, 0.93, 0.90} is 0.96.
