For the data described below select the proper statistical t

For the data described below, select the proper statistical test/tests to compare the means of each set of sample data as described below. Does the measured data suggest that a significant difference exists between the means of the samples for a values = to 0.05, 0.10 and 0.15. If not, identify which two sets of sample data have significant differences between their respective means for each a value. (Sample One versus Sample Two at a values = to 0.05,0.10 and 0.15, Sample Two versus Sample Three at a values = to 0.05,0.10 and 0.15, etc.) Justify your conclusions by comparing the probability of them being significantly different with the value of the test statistic that you chose to utilize. Organize your results in a table. For the machine screw case study and data obtainable through the link provided below. Answer the following questions and justify your answers with whatever means you see fit for each machine! Is the data normal?
