PLEASE NOTE: The csv file cannot be uploaded in the proper format. However, the steps to import data are proc reg code is all I require for the solution. What are the steps in completing this question?

Q2 (17 points) SAS Question: The file trees1.csv contains records of the volume (cubic feet), diameter (inches), and height (feet) of 40 cherry trees. (a) State the linear model without transformations relating volume (y) to the other two variables. Be sure to define any c variables that are introduced. (b) Estimate the model and use the appropriate diagnostic plots to check if any model assumptions appear to be violated. Be sure to comment on implications from each plot. (c) Consider the model with a natural logarithm transformation applied to volume and diameter. State the new model and use the appropriate diagnostic plots to check if any model assumptions appear to be violated. Be sure to comment on implications from each plot. (d) Which of the two models is preferable? In a sentence, briefly justify your answer. (e) Carefully interpret the estimated regression coefficient for height from the fitted model in (c).\f
