Suppose a group of engineers are interested in evaluating the assembly times of four machines. There are two nuisance factors to be averaged out. The first nuisance factor is program and the second nuisance factor is operator. Each machine has several programs to be used but we have time for only four to be tested. Also, the machines are operated by several operators with substantial differences in skills and experience. Match the variable name with the appropriate variable type, based on the experiment. 1) Is Time a Blocking factor, Response, or Treatment factor? 2) Is Machine a Blocking factor, Response, or Treatment factor? 3) Is Program a Blocking factor, Response, or Treatment factor? 4) Is Operator a Blocking factor, Response, or Treatment factor? Match the variable name with the appropriate effect type, based on the description. 4) Is Machine a Fixed effect or random effect? 5) Is Program a Fixed effect or random effect? 6) Is Operator a Fixed effect or random effect
