The correlation is 0.981. there is a strong positive linear relationship between a bear’s neck girth and its weight
Explanation of Solution
Given:
Calculation:
Realize they would like to view the association, and give the decision coefficient (r-sq.). To obtain the correlation value, you have to square root. However, when doing this: note that square rooting a square would not tell whether it was positive or negative, it would expect the true correlation to be positive since the greater the weight of a bear, the greater the leg. Explanation of an association (a further explanation is based on the decision coefficient) Hence, the correct option is (e)
