Can someone help with coefficient and interpretation value please

(in inches) of a tree species as a function of time after planting 4.0 6.0 9.0 24 32 49 d = Diameter (in inches) T = Time (in years) a) Find a linear regression model for the time after planting of this tree species as a function of its average trunk diameter, d. State the correlation coefficient r for the model. (Round all values to nearest 0.000 (No supporting work needed on this question.) 2.5 15 8.0 56 9.5 66 12.5 80 r= T(d) = _6.0436d +0.7596 ) State each coefficient in the equation of 7(d) with dimensional units. Then interpret the meaning of coefficient in the equation for 7(d) above in the context of this application. Coefficient Value (with units) Interpretation (in context of this data model) = D. 9778 15.5 89 This is the diameter of a free when is newly planted la at the first ye 0.7594 inches Use your model to predict the amount of time after planting for a tree that has a diameter of 20.0 i your final answer)
