 
Hi Manny, Here is the data you sent.
I would calculate the mean, the median, the range and the standard deviation for each of the two data sets. The means are very similar but the other three measures are quite different between the two groups. The decision as to which group to hire depends on many factors. Is consistency important? If so maybe group B is the better choice? Is there a training program so that the people in group A that need improving can be helped? Can one of the people in group A be given a different job? How do the manual dexterity test results relate to actual breakage? I hope this helps,
