We want to explore the impact of drinking on brain size. From 12 randomly selected adult participants, their weekly alcohol consumption (X) and their brain volumes (Y) measured from their MRI scans were recorded. A simple linear regression mode is built as Y = A + BX. From the sample data and the regression model, we computed the residual as SSR = 65 ml"2. Please estimate the variance of the responses Yi [i=1,..,12) with the sample data. Please round your answer to one decimal place
