additional question: what is your analysis and conclusion with the test results of four laboratories? Four laboratories are being used to perform chemical analyses. Samples of the same are sent to the laboratories for analysis as partof the study to determine whether or not they give, on the average, the same results. The analytical results for the 4 laboratories areas follows: use alpha = 0.05A B C D58 62 55 6061 64 54 6060 63 56 6059 59 53 6158 60 58 62ANOVA TABLE: Fill in the missing values.

The 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 alpha (a) = 0.05. This problem is a test on what population parameter? What is the null and alternative hypothesis? What are the Significance level and type of test? What standardized test statistic will be used? What is the standard test statistic? What is the Statistical Decision? What is the statistical decision in the statement form?
