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) reported were as follows: 23.01, 22.22, 22.04, 22.62,. and 22.59. Test that the average interior temperature is equal to 22.5 °C using a = 0.05. 18. This problem is a test on what population parameter? * Mean Variance/Standard Deviation Population Proportion 19. What is the null and alternative hypothesis * HO: (e = 22.5), H1: (@ = 22.5) HO: (0 = 22.5), H1: (0 > 22.5) HO: (0 = 22.5), H1: (0 < 22.5) 20. What are the Significance level and Type of test * O a = 0.05, Right-tailed O a = 0.05, left-tailed O a = 0.05, two-tailed

24. What is the Statistical Decision in statement form? *
With 0.05 level of significance, there is no sufficient evidence to support the claim that the average
interior temperature is not equal to 22.5.
With 0.05 level of significance, there is strong evidence to support the claim that the average interior
temperature is not equal to 22.5.
