Question

The following data represents the sap production for trees of various ages. use the data to answer the questions that follow: Tree Age (years) Sap Production (in mL) 7| 200 ,50| 350 10| 370 17| 380, 35| 480, 8 280 27 420 40 430 12 320 45 360 22 480 42 390 30 430 37 450 a. Create a scatterplot of the above data using age as the explanatory variable. Describe the relationship you see based on the scatterplot b. determine the linear regression equation for the data c. determine the correlation coefficient for the data d. Interpret the slope of the equation in context of the problem e. Interpret the y-intercept of the equation in context of the problem. Is this interpretation appropriate? f. Use the regression equation to approximate the sap production of a tree that is 45 years old. How does this value compare the collected data.
