12.100 Three different heat-treatment methods are being tested against four different zinc-coating techniques, with data representing the number of pounds required for a test probe to penetrate the layer of zinc coating. Metal samples have been randomly assigned to the factor levels, with two replications in each cell. For the data  shown here, use the 0.01 level of significance in drawing conclu- sions from this experiment. Determine the 95% confi- dence interval for the population mean for each factor level. (Use data file XR12100.)
