Data was collected from a sample of 27 trees with diameters between 5 and 21 inches. A regression analysis was run to determine if there is a relationship between the diameter of a tree ( x, in inches) and the tree's age (y, in years). The results of the regression are given below. Y= ax + b a= 7.12 b = 1.11 r^2= 0.845 R = 0.919 Based on the r-value, what do you conclude about the linear correlation? Based on the r-value, what do you conclude about the linear correlation? There is no linear correlation There is a strong negative linear correlation There is a weak negative linear correlation There is a weak positive linear correlation There is a strong positive linear correlation Predict the age of a tree whose diameter is 6 inches. Classify this prediction as an interpolation or extrapolation
