Serena Francis · Answer 1

A correlation coefficient is always a value in between - 1 and 1

The closest a coefficient to - 1, the correlation is a strong negative correlation

The closest a coefficient to 1, the correlation is a strong positive correlation

The closest a coefficient to 0, there is no correlation at all

The coefficient - 0.61 shows a strong negative correlation

This means that the relationship between the age and the violation is an inverse relationship; as age increases, violation decreases

Answer: option C
