To calculate the correlation coefficient (r-value) for the given data, we can use software like GeoGebra, Excel, or a scientific calculator that supports statistical functions.
However, without using technology directly, I can guide you through the process of calculating the correlation coefficient manually using the formula, or I can directly provide you with the correlation coefficient based on the data.
Given the data:
x-values: 5, 6, 7, 8, 9
y-values: 22, 29, 28, 31, 37
After calculating the correlation coefficient, the value is approximately 0.94.
Therefore, the correct response is:
0.94
