Step-by-step explanation:
We are given the following information in the question:
Correlation:
Correlation is a technique that help us to find or define a relationship between two variables.It is a measure of linear relationship between two quantities.A positive correlation means that an increase in one quantity leads to an increase in another quantityA negative correlation means with increase in one quantity the other quantity decreases.+1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship.Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.Since, the weight of an animal increases with age a correlation value of 0.65 that indicates a moderate positive linear relationship can be used.
