Textbook Question
Chapter 7.1, Problem 8E
Does It Make Sense? For Exercises 5–8, determine whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; not all of these statements have definitive answers, so your explanation is more important than your chosen answer.
- 8.

L4Q4.What correlation can be observed between x and y in the figure?
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 decreases
B. There is a statistically significant, strong, negative correlation between age and agility, suggesting that as age increases, agility decreases
C. There is a non-significant, moderate, positive correlation between age and agility, suggesting that there is no relationship between these two variables
D. There is a statistically significant, strong positive correlation between age and…
