help with a ttest involving deviations
Posted:
Nov 9, 2006 6:30 PM


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
