(5(13/11) + 4(-19/11) = 65/11 - 76/11 = -11/11 = -1) ✔️ (x = 1,\qquad y = -1) | Module
(5.6\ \textkW·h=2.016\times10^7\ \textJ) (x = 1
(t_calc= -2.13,; df\approx 22,; p\approx0.045) → Reject (H_0); the means differ at the 5 % level.
Directly use the equivalence (1\ \textkW·h=3.6\times10^6\ \textJ); multiply by 5.6.
Determinant (\det(A)=3(4)-(-2)(5)=12+10=22).
