I have been working on comparing a set of data and can't figure it out. I think it is pretty simple but I am really bad on statistics. I would really appreciate if someone out there could help.

sample	Exp A	Exp B
1	1.2	1.4
2	.5	.4
3	2.5	2.5
4	.8	.8
5	1.5	1.4
6	2.0	2.0
7	1.5	1.5

I need to prove with some statistical  terms that Exp A and Exp B can can produce same results. What Stat term can i use to compare the data? I have a total of 40 samples with similar results as above.
Please Please help.
Thanks in advance
