A researcher is conducting a study to examine the relationship between age and agility. She recruited a sample of 50 participants, ranging in age from 20 – 65 years old, and asked them to perform a series of agility tests. Afterward, participants were given an average agility score, which was then used in a correlation analysis against participant age. The results of the study are as follows [r(50) = -0.97, p < 0.001]. Identify the correct interpretation below. A. There is a non-significant, weak, negative correlation between age and agility, suggest that as age increases, agility decreasesB. There is a statistically significant, strong, negative correlation between age and agility, suggesting that as age increases, agility decreasesC. There is a non-significant, moderate, positive correlation between age and agility, suggesting that there is no relationship between these two variablesD. There is a statistically significant, strong positive correlation between age and agility, suggesting that as age increases, agility also increases

It is given that r(50) = -0.97 p < 0.001

Answered: agility decreases B. There is a…
