1. (30 points) You have observations on a random sample of 25 individuals 011 two attitude measures, X1 and X2. Assume that X ' 2 (X1, X2) comes from a population that is N501, 2). Based on your 7; = 25 sample, you compute 1E and S in the usual way. Using the sample data, you obtain a 95% condence region for ,u and one-at-atime condence intervals for ,qu and #2. These are plotted below and draw to scale
