AMS 315 Data Analysis Spring Semester, 2010 Chapter Eight and Nine Homework 8.6 A large laboratory has four types of devices used to determine the pH of soil samples. The laboratory wants to determine whether there are differences in the average readings given by these devices. The lab uses 24 soul samples having known pH in the study, and six of the samples to each device. The soil samples are tested and the response recorded is the difference between the pH reading of the device and the known pH of the soil. These values, along with summary statistics, are given in the following table. 8.8 Four populations are to be compared based on differences in their means. Suppose the population means are given as follows: μ 1 = 20 μ 2 = 20 μ 3 = 20 μ 4 = 20 Using the relationship μ i = μ + τ i , compute the values of μ and τ i . 8.23 In a 1996 article published in Technometrics, 38. pp. 11 22, the authors discuss the reliability of nuclear power plant emergency generators. To control the risk of damage to the
