  1. An article in the ASCE Journal of Energy Engineering (1999, Vol. 125, pp. 59–75) describes a study of 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 temperatures (°C) (assumed to follow a normal distribution) reported were as follows: 23.01, 22.22, 22.04, 22.62, and 22.59.

    (a) Assuming the interior temperature must be 22.5, conduct a hypothesis testing at 0.05 significance level to see if the mean temperature is 22.5.
