help with a t-test involving deviations

I have 5 numbers generated by a chemical device. Due to various
factors, each number has a total uncertainty of approximately +/- 13%.
Could someone help me figure out whether or not I have two groups

A) 833
B) 797
C) 602
D) 621
E) 647

One hypothesis is that C,D,E represent a distinct group of numbers
separate from A and B. Again, with a 13% uncertainty applied to each
of the numbers, how likely is it that those are, in fact, two groups?

Thanks,
Stu
