Answer:
r is very close to 1 because there is a very concrete relationship between the variables x and y.
Step-by-step explanation:
Given that x = age,
y = time since the subject had acquired a driving licence.
We want to know why the correlation of these variables is so close to 1.
Correlation of these variables is the mutual relationship between the two variables.
Drivers licence is only obtainable when one comes of age.
For example: Many countries don't issue drivers license to an individual below the age of 18.
The correlation is very close to 1 because there is a concrete relationship between the variable.
