Problem 3 Let us consider the linear model 91 = H+D1+l3+1f1+f1 ya = H+G1+3+T1+62 ya = #+!1+63 y4 = u+a1+64 $15 = #+02+F3+'Y2+Es ya = p+a2+6+2+ea 317 = #+a2+67 29's = #+z+fs [a] When is 3le + alo1+ 320.2 + as + 341': + asvg estimable? (bl Indicate if the following parametric functions are estimable with this model and calculate least-squares estimates and standard deviations of those estimates when possible. {(7) Test the hypothesis Ho: {:1 = as. '1'1 = v: if the values of the response variable in the proposed model are 110, 6.95, 3.31 4.19, 6.?3, 112, 3.94, 4.05
