1)A study was conducted on the thermal inertia properties of autoclaved aerated concrete used as a building material. Five samples of the material were tested in a structure, and the average interior temperature (C) reported was as follows: 23.01, 22.22, 22.04, 22.62, and 22.59. Assume variance unknown. Test the hypothesis pair H₀: = 22.5 versus H₁: 22.5.,

using =0.05.
