Question

This table displays the relationship between two variables, x and y, showing the corresponding y-values for given x-values.
x-Value y-Value
5 22
6 29
7 28
8 31
9 37
Use technology (such as GeoGebra) to find the correlation coefficient of the data. Round your r-value to two decimal places, if necessary.

Answer 1

To find the correlation coefficient (r-value) for the given data set using a tool like GeoGebra or any statistical software, you would input the x-values and corresponding y-values.

Based on the data provided:

• x-values: 5, 6, 7, 8, 9
• y-values: 22, 29, 28, 31, 37

Upon calculating the correlation using the appropriate technology, the r-value found is approximately 0.94.

Thus, the correct response is:

0.94
