Question

6. 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. Seven samples of the material were tested in a structure, and the average interior temperatures ('C) reported were as follows Do all parts below a. [S) Compute the sample mean and the sample s 23.01, 22.22, 22.64, 23.62, 24.59, 23.15, 21.83. tandard deviation (just answer, no justification needed) ANS: sample mean ANS: sample standard deviation. t μ denote the mean interior temperatures of autoclaved aerated concrete. Test the hypotheses Ho:-22.5 versus H1: μ ,22.5, using 0.05. Use based on this.region. Show all your work and clearly state your conclusion reiection region and make a decision ANS: conclusion ANS: Rejection region c. (5] Compute the P-value. What would be your conclusion at a 0.10 ANS nfidence interval for the mean interior temperatures the mean interior temperatures μ two-sided co [5] Find a 90% of autoclaved aerated concrete d. a of interior temperatures of autocaved two-sided confidence interval for the standard deviation [5] Finda 90% aerated concrete e.
