7. Weld strength experiment The data shown in Table 6.20 are a subset of the data given by Anderson and McLean

(1974) and show the strength of a weld in a steel bar. Two factors of interest were gage bar setting (the distance the weld die travels during the automatic weld cycle) and time of welding (total time of the automatic weld cycle). Assume that the levels of both factors were selected to be equally spaced.
