Question: The following table (A. Held Statistical theory with Engineering Applications John Wiley fc Sons New York. 1952) gives tensile1 st lengths of deviations from 340

The following table (A. Held Statistical theory with Engineering Applications John Wiley fc Sons New York. 1952) gives tensile1 st lengths of deviations from 340 for wires taken from nine cables to be used for a high-voltage network. Each cable is made from 12 wires. We want to know whether the mean strengths of the wires in the nine cables are the same. If the cables are different, which ones differ? Use a /'-value in your analysis ofvariance.
