Final answer:

The linear correlation coefficient, r, can be calculated using the formula: r = √(r²). Given that the coefficient of determination, r², is 0.47, the linear correlation coefficient, r, is approximately 0.6853.

Step-by-step explanation:

The linear correlation coefficient, r, can be calculated using the formula:



r = √(r²)



Given that the coefficient of determination, r², is 0.47, we can substitute this value into the formula to find the value of r:



r = √(0.47) = 0.6853



Therefore, the linear correlation coefficient, r, is approximately 0.6853.
