2. [20 points total; 10 each] You and your research team obtained the index of adiposity, basil insulin, and basal glucose values on 21 normal subjects. The data is presented in the table below. You wish to understand the strength of the relationship between these variables. a. Calculate the bivariable correlation for each pair of variables and interpret the meaning of each. b. Compute the multiple correlation coefficient and test for significance at the 0.01 level.
