... 2. Holes drilled by a human operator (M) and by a robot (R) were studied. The numbers of holes were nM = 7 and nR = 8. The obtained sample standard deviations of the hole depths were sM = 0.0435 cm and sR = 0.0131 cm. The drill hole depths are assumed to be normally distributed in both cases. Can it ...

... then you should not be using ANOVA. Most textbooks state that the ANOVA tests the null hypothesis that all the group means are equal. This is one way of looking at it. An equivalent way of stating it is that the ANOVA tests the null hypothesis that all the αi are zero. When all the αi are zero, then ...
