2. An experiment was conducted to determine the effect of four different types of tips in a hardness tester on the observed hardness of a metal alloy. Four specimens of the alloy were obtained, and each tip was tested once on each specimen, producing the following data: Specimen Туре of Tip 1 2 3 4 1 9.3 9.4 9.6 10.0 9.4 9.3 9.8 9.9 3 9.2 9.4 9.5 9.7 4 9.7 9.6 10.0 10.2 Is there any difference in hardness measurements between the tips? b. b. Use Fisher's LSD method to investigate specific differences between the tips. c. Analyze the residuals from this experiment. а.
