Answer:

  D. r = -0.905 represents a stronger correlation because |-0.905| > |0.727|

Step-by-step explanation:

You want to know which value of r indicates a stronger​ correlation: r= 0.727 or r= - 0.905.

Correlation coefficient

The correlation coefficient r is ±1 when the response variable value is perfectly predicted by the explanatory variable value. The closer the magnitude of r is to 1, the stronger the correlation. A value of r near zero indicates there is no correlation at all, and the explanatory variable has no predictive power with respect to the response variable.

  r = -0.905 indicates a stronger correlation than r = 0.727
