Q3. The impact of four different types of tips in a hardness tester on the measured hardness of a metal alloy was investigated in this experiment. Four samples of the alloy were acquired, and each tip was used once on every specimen, resulting in the following data: Type of Tip 1 2 Specimen 3 4 123+ 9.3 9.4 9.6 10.0 9.4 9.3 9.8 9.9 3 4 9.2 9.4 9.5 9.7 9.7 9.6 10.0 10.2 (a) Is there any difference in hardness measurements between the tips? Use the formulations to find SS, MSE, and F values. (b) Use Fisher's LSD method to investigate specific differences between the tips. (c) Analyze the residuals from this experiment. Put Computer outputs. Graphs and ANOVA table. Q3. The impact of four different types of tips in a hardness tester on the measured hardness of a metal alloy was investigated in this experiment.
